Especially Tate Thompson (Tom) Brady (1922-1993), to whom the paper is dedicated. Tom, assisted by his brother Pat and William E. Trout III, located most of Virginia's charcoal iron sites. The Brady's come from an iron family, Buffalo Forge, and have continued to play an important role in the story of Virginia Iron. Lyle E. Browning who first suggested I work with the Virginia Iron Industry. Lyle served on the committee, provided research, graphics, and computer assistance; acted as a sounding board for ideas; and served as editor. My children- Nancy, Meredith, Elizabeth, and James (Sandy), who supported their Dad through the years. Although they often had no idea what I was on about, they listened anyway. Work on the metal and slag samples from Albemarle Iron works was conducted by a number of people. Dr. Brent Owens, Professor of Geology at the College of William and Mary sectioned the samples and arranged for polished thin sections. Dr. Charles P. Swann, Professor Emeritus, Bartol Research Institute, University of Delaware performed the PIXE (particle-induced X-ray emission) testing. Dr. Gerry McDonnell, Senior Lecturer in Archaeological Sciences, Ancient Metallurgy Research Group, Department of Archaeological Sciences, Bradford University (United Kingdom) performed SEM (scanning electron microscope) energy dispersive X-ray analysis. Dr. Geoff Grime and Dr. Christopher Salter performed analysis on two thin sections at the Oxford University (United Kingdom) Materials Science-Based Archaeology Group. Peter Wickham King, a Ph.D. candidate at Wolverhampton University in Great Britain provided a wealth of information on the early technology and history of the British iron industry. He has done a considerable amount of research into British company and government records. Between us we have made a start on tying British ironmongers and forges to American colonial blast furnaces. But, that is another paper. Edward (Ned) Heite provided invaluable assistance on the Chesapeake iron industry. He also served as a sounding board for ideas as the paper developed. William W. Reynolds, who wrote an excellent article on the Albemarle Iron Works in 1992. Bill answered numerous e-mailed queries and provided copies of all of his research notes; letters from Tom Brady; the Froehling & Robertson, Inc. analysis of the Old's Forge iron; and field notes of a visit to the Albemarle sites w ith Tom Brady in 1990. Assistance in the areas of bloomery and blast furnace operations, metallurgy, and archaeometallurgy was provided by a number of people, especially: Dr. Robert B. Gordon, Professor of Geophysics and Applied Mechanics at Yale University; Dr. Martha Goodway, Archaeometallurgist, The Smithsonian Center for Materials Research and Education, Smithsonian Institution; Dr. Christopher Salter, Dept, of Materials, Oxford University; Dr. Ian Freestone, British Museum; Dr. Ingo Keesmann, Arbeitsgruppe Archaeometallurgie, Institut fuer Geowissenschaften, Johannes Gutenberg- Universitaet Mainz; Dr. David J. Killick, Associate Professor of Anthropology, University of Arizona; Dr. Henry Cleere, World Heritage Coordinator, International Council on Monuments and Sites (ICOMOS), Paris; Jeremy Hodgkinson, Chairman, Wealden Iron Research Group; David Crossley, Reader, Sheffield University; and Dr. J. E. (Ned) Rehder, Senior Research Associate in the Department of Metallurgy and Materials Science, University of Toronto The arch-metals group provided answers and explained the sometimes extremely technical aspects of metallurgy to an archaeologist. Research assistance was provided by the staffs of the Virginia Historical Society; State Library of Virginia; Archives of the Virginia Department of Historic Resources (especially Jean McRae); University of Virginia Alderman Library and Special Collections; Knight-Capron Library, Lynchburg College; and the University Manuscripts and Rare Books Department, Swem Library, College of William and Mary. The Interlibrary Loan Section of the Library of Virginia (especially David Grabarek), and through them libraries all over the world, was instrumental in providing research material. A special thanks to Dr. Alan P. Druschitz, Director of Materials Development at INTERMET, Lynchburg, Virginia, who spent half a day answering questions and showing me how cast iron is made and cast today at the Archer River plant. He brought blast furnace operations alive. Lee Sauder and Skip Williams of Rockbridge Forge. We have helped each other with research materials. But, they gave me the opportunity to make iron at their experimental bloomery in Lexington, Virginia. There is something elemental about a red hot bloom of iron. Making iron by hand and consolidating the bloom with sledge hammers gives one a better appreciation of 18th century ironmaking. And finally, my Committee, Dr. Norman Barka, Dr. Theodore Reinhart, and Lyle Browning, who allowed me to go where my research took me. And gave me the time to get it right.

This work focuses on the effects of the carburizing temperature and time on the mechanical properties of mild steel carburized with activated carbon, at 850, 900 and 950 °C, soaked at the carburizing temperature for 15 and 30 minutes, quenched in oil, tempered at 550 °C and held for 60 minutes. Prior carburization process, standard test samples were prepared from the as received specimen for tensile and impact tests. After carburization process, the test samples were subjected to the standard test and from the data obtained, ultimate tensile strength, engineering strain, impact strength, Youngs’ moduli were calculated. The case and core hardness of the carburized tempered samples were measured. It was observed that the mechanical properties of mild steels were found to be strongly influenced by the process of carburization, carburizing temperature and soaking time at carburizing temperature. It was concluded that the optimum combination of mechanical properties is achieved at the carburizing temperature of 900 °C followed by oil quenching and tempering at 550 °C.

  • 5. Sirhowy Ironworks
    Great Archaeological Sites in Blaenau Gwent 5. SIRHOWY IRONWORKS There were a number of ironworks in the area now covered by Blaenau Gwent County Borough, which provided all the raw materials they needed – iron ore, limestone and fuel, charcoal at first but later coal to make coke. The Sirhowy ironworks (SO14301010) are the only one where there is still something to see. The works were opened in 1778 with one blast furnace. Although it was originally blown by water power, in 1799 the owners invested in a Boulton and Watt steam engine. This gave them enough power to blow a second furnace, which started production in 1802. In the early years of the 19th century, the pig iron produced at Sirhowy was sent to the Tredegar works a little further down the valley where it was refined, until 1818 when the Sirhowy works were sold and started to send its pig iron to Ebbw Vale. A third furnace was added in 1826 and a fourth in 1839. But by the 1870s iron smelting at Sirhowy was no longer profitable, and the works finally closed in 1882. Like all ironworks in South Wales, the furnaces were built against a steep bank which enabled the ironworkers to load the charge of iron ore, limestone and coke or charcoal fuel more easily at the top of the furnace. All that is now left now are the remains of a bank of blast furnaces with the arches that would originally have linked them to the casting houses in front, and the building that originally housed the waterwheel.

Essenhigh, Yurii G. Utkin, Chad Bernard, Igor V. Adamovich *, J. William Rich Nonequilibrium Thermodynamics Laboratories, Department of Mechanical Engineering, The Ohio State University, Columbus, OH 43202, USA Received 3 September 2006; accepted 21 September 2006 Available online 30 September 2006 Abstract The gas-phase Boudouard disproportionation reaction between two highly vibrationally excited CO molecules in the ground elec- tronic state has been studied in optically pumped CO. The gas temperature and the CO vibrational level populations in the reaction region, as well as the CO2 concentration in the reaction products have been measured using FTIR emission and absorption spectroscopy. The results demonstrate that CO2 formation in the optically pumped reactor is controlled by the high CO vibrational level populations, rather than by CO partial pressure or by flow temperature. The disproportionation reaction rate constant has been determined from the measured CO2 and CO concentrations using the perfectly stirred reactor (PSR) approximation. The reaction activation energy, 11.6 ± 0.3 eV (close to the CO dissociation energy of 11.09 eV), was evaluated using the statistical transition state theory, by comparing the dependence of the measured CO2 concentration and of the calculated reaction rate constant on helium partial pressure. The dispro- À18 3 portionation reaction rate constant measured at the present conditions is kf =(9±4)· 10 cm /s. The reaction rate constants obtained from the experimental measurements and from the transition state theory are in good agreement.

Silver (Part 1) Peter Hemingray In 1996 and 1997 The Testimony published two two-part articles under the title, “Metals in the Bible”, in which we looked at iron and copper.1 We considered the ancient technology of iron, and how this knowledge helps illuminate the Biblical references to it. In particular, we saw how the introduction of iron during the period of the conquest affected the Israelites, who had to overcome superior technology through the power of God. For copper (or brass, as the AV terms it) the ancient metalworking methods were illuminated with illustrations from Timnah in Palestine, and we argued for the symbology of copper in the Bible being primarily that of strength, and only rarely that of the strength of sin. The intention was to complete these studies on metals of the Bible by considering silver, then gold. This we have now done in two further two-part articles to be published in this and the coming months, God willing.

Dross also Dross is a reaction product which is formed from occurs in the form of long stringers instead of Mg treatment and during subsequent reoxidation concentrated “slag like” areas. When it occurs in of Mg rejected from the molten metal before it this string like form it acts like cracks or flake solidifies. It is therefore just another word for a graphite in the structure and so fatigue strength specific type of slag (reaction product). and impact strength of the material are lowered considerably. The reaction binds magnesium with sulphur, oxygen and silicon and forms continuously. This “dross” is light weight and so it will generally be found in the upper surfaces and under cores, but it can be entrained throughout the metal as well, especially with colder pouring tempera - tures. It is very difficult to completely avoid the reaction of magnesium with these other elements, since we need magnesium to form nodules. We are always confronted with the problem of dross in the production of Ductile Iron. WHAT IS PROMOTING “DROSS ” AND WHAT CAN BE DONE TO KEEP THE “DROSS ” OUT OF THE CASTING ? Since “dross” is always connected with magnesium, it is necessary to keep the magnesium level as low as possible. Good inoculation practice with some late inoculation in conjunction with sufficient magnesium will When looking at “dross” in the microscope you produce nice round small nodules. See will almost always find flake graphite in Suggestion Sheet 76.
