Metallurgy - Wikipedia. Metallurgy is a domain of materials science and engineering that studies the physical and chemical behaviour of metallicelements, their intermetallic compounds, and their mixtures, which are called alloys. Metallurgy is also the technology of metals: the way in which science is applied to the production of metals, and the engineering of metal components for usage in products for consumers and manufacturers. The production of metals involves the processing of ores to extract the metal they contain, and the mixture of metals, sometimes with other elements, to produce alloys. Metallurgy is distinguished from the craft of metalworking, although metalworking relies on metallurgy, as medicine relies on medical science, for technical advancement. Metallurgy is subdivided into ferrous metallurgy (sometimes also known as black metallurgy) and non- ferrous metallurgy or colored metallurgy. Ferrous metallurgy involves processes and alloys based on iron while non- ferrous metallurgy involves processes and alloys based on other metals. MSc Petroleum Geoscience, University of London, provides specialist knowledge, practical and technical skills for the petroleum industry and exploration. Metallurgy is a domain of materials science and engineering that studies the physical and chemical behaviour of metallic elements, their intermetallic compounds, and. The production of ferrous metals accounts for 9. Small amounts of natural gold have been found in Spanish caves used during the late Paleolithic period, c. The first evidence of this extractive metallurgy dates from the 5th and 6th millennia BC. To date, the earliest evidence of copper smelting is found at the Belovode site. However, the ultimate beginnings cannot be clearly ascertained and new discoveries are both continuous and ongoing. Drilling operation and components 1. Drilling Operations 2.

Boxes colors: arsenic is in brown, copper in red, tin in grey, iron in reddish brown, gold in yellow, silver in white and lead in black. Yellow area stands for arsenic bronze, while grey area stands for tin bronze. These first metals were single ones or as found. About 3. 50. 0 BC, it was discovered that by combining copper and tin, a superior metal could be made, an alloy called bronze, representing a major technological shift known as the Bronze Age. The extraction of iron from its ore into a workable metal is much more difficult than for copper or tin. The word petroleum comes from Greek: . The term was found (in the spelling.

BC, beginning the Iron Age. The secret of extracting and working iron was a key factor in the success of the Philistines. This includes the ancient and medieval kingdoms and empires of the Middle East and Near East, ancient Iran, ancient Egypt, ancient Nubia, and Anatolia (Turkey), Ancient Nok, Carthage, the Greeks and Romans of ancient Europe, medieval Europe, ancient and medieval China, ancient and medieval India, ancient and medieval Japan, amongst others. Many applications, practices, and devices associated or involved in metallurgy were established in ancient China, such as the innovation of the blast furnace, cast iron, hydraulic- powered trip hammers, and double acting piston bellows. Agricola has been described as the . In order to convert a metal oxide or sulphide to a purer metal, the ore must be reduced physically, chemically, or electrolytically. Extractive metallurgists are interested in three primary streams: feed, concentrate (valuable metal oxide/sulphide), and tailings (waste). After mining, large pieces of the ore feed are broken through crushing and/or grinding in order to obtain particles small enough where each particle is either mostly valuable or mostly waste. Concentrating the particles of value in a form supporting separation enables the desired metal to be removed from waste products. Mining may not be necessary if the ore body and physical environment are conducive to leaching. Leaching dissolves minerals in an ore body and results in an enriched solution. The solution is collected and processed to extract valuable metals. Ore bodies often contain more than one valuable metal. Tailings of a previous process may be used as a feed in another process to extract a secondary product from the original ore. Additionally, a concentrate may contain more than one valuable metal. That concentrate would then be processed to separate the valuable metals into individual constituents. Common engineering metals include aluminium, chromium, copper, iron, magnesium, nickel, titanium and zinc. These are most often used as alloys. Much effort has been placed on understanding the iron- carbon alloy system, which includes steels and cast irons. Plain carbon steels (those that contain essentially only carbon as an alloying element) are used in low- cost, high- strength applications where weight and corrosion are not a problem. Cast irons, including ductile iron, are also part of the iron- carbon system. Stainless steel or galvanized steel are used where resistance to corrosion is important. Aluminium alloys and magnesium alloys are used for applications where strength and lightness are required. Copper- nickel alloys (such as Monel) are used in highly corrosive environments and for non- magnetic applications. Nickel- based superalloys like Inconel are used in high- temperature applications such as gas turbines, turbochargers, pressure vessels, and heat exchangers. For extremely high temperatures, single crystal alloys are used to minimize creep. Production. This involves the production of alloys, the shaping, the heat treatment and the surface treatment of the product. The task of the metallurgist is to achieve balance between material properties such as cost, weight, strength, toughness, hardness, corrosion, fatigue resistance, and performance in temperature extremes. To achieve this goal, the operating environment must be carefully considered. In a saltwater environment, ferrous metals and some aluminium alloys corrode quickly. Metals exposed to cold or cryogenic conditions may endure a ductile to brittle transition and lose their toughness, becoming more brittle and prone to cracking. Metals under continual cyclic loading can suffer from metal fatigue. Metals under constant stress at elevated temperatures can creep. Metalworking processes. The resulting melted metal reaches a substrate to form a melt pool. By moving the laser head, it is possible to stack the tracks and build up a three- dimensional piece. D printing – Sintering or melting powder metal in a very small point on a moving 'print head' moving in 3. D space to make any object to shape. Cold- working processes, in which the product’s shape is altered by rolling, fabrication or other processes while the product is cold, can increase the strength of the product by a process called work hardening. Work hardening creates microscopic defects in the metal, which resist further changes of shape. Various forms of casting exist in industry and academia. These include sand casting, investment casting (also called the . Common heat treatment processes include annealing, precipitation strengthening, quenching, and tempering. Quenching is the process of cooling a high- carbon steel very quickly after heating, thus . There is a balance between hardness and toughness in any steel; the harder the steel, the less tough or impact- resistant it is, and the more impact- resistant it is, the less hard it is. Tempering relieves stresses in the metal that were caused by the hardening process; tempering makes the metal less hard while making it better able to sustain impacts without breaking. Often, mechanical and thermal treatments are combined in what are known as thermo- mechanical treatments for better properties and more efficient processing of materials. These processes are common to high- alloy special steels, superalloys and titanium alloys. Plating. It involves bonding a thin layer of another metal such as gold, silver, chromium or zinc to the surface of the product. It is used to reduce corrosion as well as to improve the product's aesthetic appearance. Thermal spraying. In metallography, an alloy of interest is ground flat and polished to a mirror finish. The sample can then be etched to reveal the microstructure and macrostructure of the metal. The sample is then examined in an optical or electron microscope, and the image contrast provides details on the composition, mechanical properties, and processing history. Crystallography, often using diffraction of x- rays or electrons, is another valuable tool available to the modern metallurgist. Crystallography allows identification of unknown materials and reveals the crystal structure of the sample. Quantitative crystallography can be used to calculate the amount of phases present as well as the degree of strain to which a sample has been subjected. Conferences. From the start of the conference sequence in 2. Friedrichshafen it was host of the most relevant metallurgists from all countries of the world. The European Metallurgical Conference is organized by GDMB Society of Metallurgists and Miners. See also. 1. 97. 9.^Oxford English Dictionary, accessed 2. January 2. 01. 1^.

SuDoKu-Cracker offers seven. As Fitz confesses in . Some of the plotlines in the cases took as their starting point real events such as the Hillsborough disaster, while others were purely fictional with only tangential ties to actual events. Several different psychotic types were explored during the run of the show with increasingly complex psychological motivations that, as the series entered the middle of the second series, began to expand beyond the criminals being investigated to the regular cast members. As the series moved forward the storylines became as much about the interactions of the regulars as it was about the crimes. In many later episodes, in fact, the crimes often became background to intense, provocative explorations of the police officers' reactions to the crimes they investigated. To emphasise how fine a line the police (and Fitz) walk in their close association with criminals, all three series featured several stories in which the police themselves commit criminal acts or become victims of crime. Characters. Fitz often clashes with the police, particularly DCI Bilborough, over his theories, which are usually right but on occasion can make worse an already tense situation. E Prime Serial Number CrackersHe has a very rocky relationship with his wife Judith and an on- off relationship with Jane Penhaligon, often going from one to the other. The character was named after the English poet and writer Edward Fitz. Gerald, according to series creator Jimmy Mc. Govern. Coltrane won three consecutive BAFTA Awards for the role, a streak only matched by Michael Gambon, Helen Mirren and Julie Walters. Christopher Eccleston as DCI David Bilborough (Series 1, 2. Detective Chief Inspector who first hires Fitz. A stubbornly narrow- minded man, he shows little to no interest in truth or justice and frequently clashes with Fitz over their ideals. He appears excessively desperate to succeed and often fails in the process, incurring the disdain of the Chief Super, but has occasional moments of integrity (usually involving Penhaligon). His death at the hands of Albie Kinsella in . He turns out to be a far more strict and abrasive boss, frequently at odds with his officers (particularly Jimmy Beck) and the Chief Super. As an older man, he shows more tolerance of the . Also unlike Bilborough, however, he values the truth above a fitting result and thus has a much better working relationship with Fitz, although he briefly fires him when Fitz unknowingly persuades Wise's estranged wife to file for separation. A subplot throughout the series is her struggle to be taken seriously in the . Fitz finds solace in her when he and his wife are separated, but their relationship is strained more than once by Fitz standing her up, Bilborough's death and her rape, the last of which profoundly disturbs her. After Fitz goes back to his pregnant wife at a time when she needs him most, it serves as the final straw for Penhaligon; Judith Fitzgerald's hatred for her does not help matters. She definitively ends Fitz's hope for a reconciliation in . In the same episode she tells Judith she is resigning from the police force; however, in the special episode . From the beginning he is shown to be unstable, often willing (even eager) to get violent with suspects; Bilborough (whom he idolizes) is then forced to reign him in, despite their shared lack of interest in the truth. He also has a deeply- rooted misogynistic streak, stemming from an experience when he emigrated to England as a boy and was shunned by everyone in school except some girls, who showed him . Bilborough's murder - which Fitz spitefully but correctly tells him he could have prevented - hits him so hard that he falls into a guilt- ridden depression, rapes Penhaligon, and ultimately commits murder- suicide. Barbara Flynn as Judith Fitzgerald (Series 1- 3, special episode . Fed up with Fitz's addiction to gambling, she leaves him twice and at one point attempts to divorce him after falling for a therapist called Graham. Despite this, she still loves Fitz, and reluctantly makes attempts to repair their relationship, which rarely last. When she falls into a depression after learning of Fitz's affair with Penhaligon and the birth of their third child fails to improve their marriage, Judith seeks solace with Fitz's brother, Danny, and very nearly begins an affair of her own with him. She harbors a deep dislike for Penhaligon, at one point going so far as to tell her that her rape was a kind of . He and Fitz share a love- hate relationship brought on by Fitz's habit of driving Judith away, and he takes a particular dislike to Penhaligon (who is nearer to his age than Fitz's) when Fitz begins an affair with her; in . In the same episode, he helps Fitz translate some esoteric religious symbolism, in the process showing a level of knowledge and intelligence in contrast to his normal attitude. His kidnapping and near- death experience in . Though what effect this has on her is only implied, she is shown to be upset about it. Having appeared as a youngster in the first three series, the role was re- cast for the special episode . Evans plays James in the second special . Penhaligon appears to have somewhat taken a shine to Giggs, as she is particularly upset by his brutal death. Colin Tierney as DC Bobby Harriman (Series 2): DS Giggs' replacement following his murder. Appearing timid at first, his self- confidence soon grows and he proves to be a reasonably competent officer despite occasional mistakes. In his first appearance he is caught leaking information about a murder case to the press, but Bilborough declines to punish him for it. After being shut out of the same investigation, Fitz uses him to present his theories to the squad (though Penhaligon sees through this). In fact, he is one of the few officers in the unit who is even vaguely receptive to Fitz. He also helps to capture a rapist- murderer at the end of . He and Fitz dislike each other almost instantly; besides trading barbs, they tend to call one another out on their personal and professional failings. Similar to Bilborough, he is shown to be not all that competent but desperate to succeed. It is mentioned that he was demoted from DI to DC, something he is occasionally mocked for. He has an implied romantic fling with Penhaligon, much to Fitz' dismay, and is protective of her to the point of being overbearing. He is also friends with DC Skelton, although after failing to realize someone he interviewed was a murderer he tries to make Skelton take the blame, angering both him and Penhaligon. Wise is frequently and openly disdainful of Temple, and agrees with Fitz that his romantic intentions with Penhaligon are somewhat deluded. Stan Finni as Sgt. Smith (Series 1): The only black officer on the force. A minor character, he most notably arrests Fitz in . He also appears briefly in . Smith, although he has a much more hands- on involvement in several cases. He becomes close friends with DC Temple. Following Beck's death, Skelton is promoted from PC to DC and proves to be a smart, resourceful officer. Clive Russell as Danny Fitzgerald (Series 2- 3): Fitz's estranged brother. They briefly reconcile after the death of their mother, but their relationship becomes strained when Danny realises the stress Judith is going through thanks to Fitz and resents him for it, becoming a kind of surrogate husband/father in the household. Fitz, in turn, dismisses him as an unremarkable, eager- to- please busybody. Danny and Judith are clearly attracted to one another, and she very nearly begins an affair with him in . Russell was cast at Coltrane's recommendation. Amelia Bullmore (Series 1. Isobel Middleton (Series 2. Catriona Bilborough: David Bilborough's wife and later widow. She is said to be pregnant with their first child in . When Fitz tells her she has nothing to feel guilty about, she reminds him about his falling out with her husband, insisting he would never lock up an innocent man and come home with a clean conscience; Fitz, in a moment of compassion, lies that Bilborough had caught the right man. Catriona remains in touch with Jimmy Beck, who dotes on and attends the baptism of her son in . Catriona, however, insists that no one can replace David. Edward Peel as the Chief Super (Series 1- 3): The head of Anson Road CID. His rather boorish nature does not endear him to others, and he has a combative relationship with Fitz, Bilborough and Wise (despite choosing the latter to replace Bilborough). Perhaps his only compassionate moment comes when informing Catriona Bilborough of her husband's death. He frequently questions or belittles the decisions of Bilborough and Wise, the latter of whom he gets into furious arguments with, and tells Fitz that he is only hired for good publicity.

Data Center Top- of- Rack Architecture Design. What You Will Learn. Forward- looking IT departments are preparing their data centers for the future by integrating support for 1. Gigabit Ethernet and a unified network fabric into their switching and cabling strategies. Since the typical data center lifecycle is 1. Cabling architectures, if not chosen correctly, could force an early replacement of the cabling infrastructure to meet connectivity requirements as the network and computer technologies evolve. Today’s data centers deploy a variety of cabling models and architectures. With the migration from Gigabit Ethernet to 1. Gigabit Ethernet, cabling and network switching architectures are being reevaluated to help ensure a cost- effective and smooth data center transition. The choice of cabling architecture will affect throughput, expandability, sustainability, optimum density, energy management, total cost of ownership (TCO) and return on investment (ROI). Anticipating growth and technological changes can be difficult, but the data center should be able to respond to growth and changes in equipment, standards, and demands while remaining manageable and reliable.
This document examines the use of the top- of- rack (To. R) cabling and switching model for next- generation data center infrastructure. It explores current 1. Gigabit Ethernet cabling choices and provides a solution architecture based on To.

Data center managers and facilities administrators will choose cabling architectures based on various factors. The To. R model offers a clear access- layer migration path to an optimized high- bandwidth network and cabling facilities architecture that features low capital and operating expenses and supports a “rack- and- roll” computer deployment model that increases business agility. The data center’s access layer, or equipment distribution area (EDA), presents the biggest challenge to managers as they choose a cabling architecture to support data center computer connectivity needs. The To. R network architecture and cabling model proposes the use of fiber as the backbone cabling to the rack, with copper and fiber media for server connectivity at the rack level. Introduction. The data center landscape is changing rapidly. IT departments building new data centers, expanding existing data center footprints, or updating racks of equipment all have to design a cabling and switching architecture that supports rapid change and mobility and accommodate transitions to 1. Gigabit Ethernet over time. The main factors that IT departments must address include the following. Many IT departments are ordering preconfigured racks of equipment with integrated cabling and switching and as many as 9. The time required to commission new racks and decommission old ones is now a matter of hours rather than days or weeks. Because different racks have different I/O requirements, data center switching and cabling strategies must support a wide variety of connectivity requirements at any rack position. Some server racks are populated with servers requiring between five and seven Gigabit Ethernet connections and two Fibre Channel SAN connections each. Racks today can be equipped with Gigabit Ethernet or 1. Gigabit Ethernet or a unified network fabric with Fibre Channel over Ethernet (FCo. E). Virtualization is one of the main areas of focus for IT decision makers. Estimates suggest that the server virtualization market will grow by 4. The change to virtualization can be disruptive and necessitate a redesign of the networking infrastructure to gain all the benefits of the virtualized computer platform. The challenge facing data centers today is how to support the modularity and flexibility that is needed to promote business agility and maintain a company’s competitive edge. The same strategy that allows the intermixing of different rack types and I/O requirements must also support a varied set of connectivity options including Gigabit Ethernet and 1. Gigabit Ethernet as well as a unified network fabric. Why Use Top- of- Rack Architecture Rapidly changing business requirements impose a corresponding need for flexibility and mobility in data centers. Because of the significant cost of building a new data center, designing an infrastructure that provides the flexibility to meet business objectives while increasing ROI is an IT imperative. By building the data center infrastructure—power and cooling, cabling, etc.—in a modular fashion, data center flexibility can be increased, which in turn improves business agility. Many organizations are now deploying modular data centers. IT departments are increasingly deploying not just servers but racks of servers at a time. Racks of servers, blade systems, and integrated rack- and- blade systems are often purchased in preconfigured racks with power, network, and storage cabling preinstalled so that racks can be commissioned within hours, not days, from the time they arrive on the loading dock. While server form factors are evolving, and some racks can host up to 9. To. R solutions complement rack- at- a- time deployment by simplifying and shortening cable runs and facilitating the replication of rack configurations. This rack- and- roll deployment model offers a solution by placing switching resources in each rack so that server connectivity can be aggregated and interconnected with the rest of the data center through a small number of cables connected to end- of- row (Eo. R) access- or aggregation- layer switches. The TIA/EIA- 9. 42 specification provides a simple reference for data center cabling that supports different cabling schemes, Eo. R or To. R, to meet differing needs from a physical and operational perspective. The To. R model defines an architecture in which servers are connected to switches that are located within the same or adjacent racks, and in which these switches are connected to aggregation switches typically using horizontal fiber- optic cabling. To. R switching allows oversubscription to be handled at the rack level, with a small number of fiber cables providing uniform connectivity to each rack. The advantage of this solution is that horizontal fiber can support different I/O connectivity options, including Gigabit Ethernet and 1. Gigabit Ethernet as well as Fibre Channel. The use of fiber from each rack also helps protect infrastructure investments as evolving standards, including 4. Gigabit Ethernet, are more likely to be implemented using fiber before any other transmission mechanism. By limiting the use of copper to within racks, the To. R model isolates the cabling that changes most often to the parts of the data center that change most frequently: the racks themselves. The use of fiber runs from racks provides a flexible data center cabling infrastructure that supports the transition from Gigabit Ethernet to 1. Gigabit Ethernet now, while enabling transition to 4. Gigabit Ethernet in the future. Modular Data Center Infrastructure. The cabling and infrastructure design for a modern data center is governed by multiple factors. The TIA/EIA- 9. 42 Telecommunications Infrastructure Standard for Data Centers provides guidelines for data center cabling infrastructure that customers can adopt as a guide in the data center cabling and planning process. Other standards, such as BICSI, provide guidelines for data center cabling and implementation. The TIA/EIA- 9. 42 cabling specification considers the need for flexibility, scalability, reliability, and space management (http: //www. While the standard provides guidelines, specific design elements will vary with each data center. General considerations that apply to all data centers include. Figure 1 shows a mapping of the logical network architecture to the physical infrastructure. TIA/EIA- 9. 42 Logical Layout. The EDA in the TIA/EIA- 9. Traditional structured copper cabling with a mix of fiber if needed for SAN or high- speed server connectivity is used to connect the EDA to the HDA. The environment requires careful planning to help ensure that the structured cabling meets the initial design requirements with enough room for growth. In cases where server racks are not yet in place or without the physical infrastructure needed to support rack- level flexibility, a zone distribution area (ZDA) cabling model is used. The ZDA allows for structured cabling to be placed under the floor or above the rack in anticipation of future server racks requiring connectivity to the network equipment that may be housed in the HDA. The ZDA follows a structured cabling model to the HDA. The primary difference in the horizontal cabling model between the ZDA and EDA is that the cables are terminated in the EDA racks, whereas the ZDA uses zone distribution blocks located outside the server racks. The To. R cabling and network architecture in Figure 1 optimizes the requirement for horizontal cabling from the server rack by placing the To. R aggregation device at the top of the server rack. Actual placement of the To. R device may vary based on customer requirements (for example, in or above the server rack or To. R aggregation per two or three server racks) and seeks to optimize customer requirements for density, cabling, and design methodology. The aggregation of the To. R device will be in the HDA based on the specific TIA/EIA reference cabling model deployed. The To. R cabling design model follows a logical network layer construct in which the server network connectivity is aggregated at the rack level in the network access layer. The access layer is in turn connected to the network aggregation layer. The To. R model uses fiber as the backbone cabling infrastructure that connects the EDA with the HDA and main distribution area (MDA). The To. R model augments the TIA/EIA- 9. Figure 1 by extending fiber as the backbone cabling of choice to the EDA or server rack. The amount of fiber required will vary based on design requirements. For example, in a migration- type design in which a To. Brent Ozar Unlimited - SQL Server Consulting and Training. Chicago and online taught by Brent for $3,9.
