2 Champion, William
SUBJECT AREA: Metallurgy[br]b. 1710 Bristol, Englandd. 1789 England[br]English metallurgist, the first to produce metallic zinc in England on an industrial scale.[br]William, the youngest of the three sons of Nehemiah Champion, stemmed from a West Country Quaker family long associated with the metal trades. His grandfather, also called Nehemiah, had been one of Abraham Darby's close Quaker friends when the brassworks at Baptist Mills was being established in 1702 and 1703. Nehemiah II took over the management of these works soon after Darby went to Coalbrookdale, and in 1719, as one of a group of Bristol copper smelters, he negotiated an agreement with Lord Falmouth to develop copper mines in the Redruth area in Cornwall. In 1723 he was granted a patent for a cementation brass-making process using finely granulated copper rather than the broken fragments of massive copper hitherto employed.In 1730 he returned to Bristol after a tour of European metallurgical centres, and he began to develop an industrial process for the manufacture of pure zinc ingots in England. Metallic zinc or spelter was then imported at great expense from the Far East, largely for the manufacture of copper alloys of golden colour used for cheap jewellery. The process William developed, after six years of experimentation, reduced zinc oxide with charcoal at temperatures well above the boiling point of zinc. The zinc vapour obtained was condensed rapidly to prevent reoxidation and finally collected under water. This process, patented in 1738, was operated in secret until 1766 when Watson described it in his Chemical Essays. After encountering much opposition from the Bristol merchants and zinc importers, William decided to establish his own integrated brassworks at Warmley, five meals east of Bristol. The Warmley plant began to produce in 1748 and expanded rapidly. By 1767, when Warmley employed about 2,000 men, women and children, more capital was needed, requiring a Royal Charter of Incorporation. A consortium of Champion's competitors opposed this and secured its refusal. After this defeat William lost the confidence of his fellow directors, who dismissed him. He was declared bankrupt in 1769 and his works were sold to the British Brass Company, which never operated Warmley at full capacity, although it produced zinc on that site until 1784.[br]Bibliography1723, British patent no. 454 (cementation brass-making process).1738, British patent no. 564 (zinc ingot production process).1767, British patent no. 867 (brass manufacture wing zinc blende).Further ReadingJ.Day, 1973, Bristol Brass: The History of the Industry, Newton Abbot: David \& Charles.A.Raistrick, 1970, Dynasty of Ironfounders: The Darbys and Coalbrookdale, Newton Abbot: David \& Charles.J.R.Harris, 1964, The Copper King, Liverpool University Press.ASD -

12 Rosenhain, Walter
SUBJECT AREA: Metallurgy[br]b. 24 August 1875 Berlin, Germanyd. 17 March 1934 Kingston Hill, Surrey, England[br]German metallurgist, first Superintendent of the Department of Metallurgy and Metallurgical Chemistry at the National Physical Laboratory, Teddington, Middlesex.[br]His family emigrated to Australia when he was 5 years old. He was educated at Wesley College, Melbourne, and attended Queen's College, University of Melbourne, graduating in physics and engineering in 1897. As an 1851 Exhibitioner he then spent three years at St John's College, Cambridge, under Sir Alfred Ewing, where he studied the microstructure of deformed metal crystals and abandoned his original intention of becoming a civil engineer. Rosenhain was the first to observe the slip-bands in metal crystals, and in the Bakerian Lecture delivered jointly by Ewing and Rosenhain to the Royal Society in 1899 it was shown that metals deformed plastically by a mechanism involving shear slip along individual crystal planes. From this conception modern ideas on the plasticity and recrystallization of metals rapidly developed. On leaving Cambridge, Rosenhain joined the Birmingham firm of Chance Brothers, where he worked for six years on optical glass and lighthouse-lens systems. A book, Glass Manufacture, written in 1908, derives from this period, during which he continued his metallurgical researches in the evenings in his home laboratory and published several papers on his work.In 1906 Rosenhain was appointed Head of the Metallurgical Department of the National Physical Laboratory (NPL), and in 1908 he became the first Superintendent of the new Department of Metallurgy and Metallurgical Chemistry. Many of the techniques he introduced at Teddington were described in his Introduction to Physical Metallurgy, published in 1914. At the outbreak of the First World War, Rosenhain was asked to undertake work in his department on the manufacture of optical glass. This soon made it possible to manufacture optical glass of high quality on an industrial scale in Britain. Much valuable work on refractory materials stemmed from this venture. Rosenhain's early years at the NPL were, however, inseparably linked with his work on light alloys, which between 1912 and the end of the war involved virtually all of the metallurgical staff of the laboratory. The most important end product was the well-known "Y" Alloy (4% copper, 2% nickel and 1.5% magnesium) extensively used for the pistons and cylinder heads of aircraft engines. It was the prototype of the RR series of alloys jointly developed by Rolls Royce and High Duty Alloys. An improved zinc-based die-casting alloy devised by Rosenhain was also used during the war on a large scale for the production of shell fuses.After the First World War, much attention was devoted to beryllium, which because of its strength, lightness, and stiffness would, it was hoped, become the airframe material of the future. It remained, however, too brittle for practical use. Other investigations dealt with impurities in copper, gases in aluminium alloys, dental alloys, and the constitution of alloys. During this period, Rosenhain's laboratory became internationally known as a centre of excellence for the determination of accurate equilibrium diagrams.[br]Principal Honours and DistinctionsFRS 1913.

13 Merica, Paul Dyer
SUBJECT AREA: Metallurgy[br]b. 17 March 1889 Warsaw, Indiana, USAd. 20 October 1957 Tarrytown, New York, USA[br]American physical metallurgist who elucidated the mechanism of the age-hardening of alloys.[br]Merica graduated from the University of Wisconsin in 1908. Before proceeding to the University of Berlin, he spent some time teaching in Wisconsin and in China. He obtained his doctorate in Berlin in 1914, and in that year he joined the US National Bureau of Standards (NBS) in Washington. During his five years there, he investigated the causes of the phenomenon of age-hardening of the important new alloy of aluminium, Duralumin.This phenomenon had been discovered not long before by Dr Alfred Wilm, a German research metallurgist. During the early years of the twentieth century, Wilm had been seeking a suitable light alloy for making cartridge cases for the Prussian government. In the autumn of 1909 he heated and quenched an aluminium alloy containing 3.5 per cent copper and 0.5 per cent magnesium and found its properties unremarkable. He happened to test it again some days later and was impressed to find its hardness and strength were much improved: Wilm had accidentally discovered age-hardening. He patented the alloy, but he made his rights over to Durener Metallwerke, who marketed it as Duralumin. This light and strong alloy was taken up by aircraft makers during the First World War, first for Zeppelins and then for other aircraft.Although age-hardened alloys found important uses, the explanation of the phenomenon eluded metallurgists until in 1919 Merica and his colleagues at the NBS gave the first rational explanation of age-hardening in light alloys. When these alloys were heated to temperatures near their melting points, the alloying constituents were taken into solution by the matrix. Quenching retained the alloying metals in supersaturated solid solution. At room temperature very small crystals of various intermetallic compounds were precipitated and, by inserting themselves in the aluminium lattice, had the effect of increasing the hardness and strength of the alloy. Merica's theory stimulated an intensive study of hardening and the mechanism that brought it about, with important consequences for the development of new alloys with special properties.In 1919 Merica joined the International Nickel Company as Director of Research, a post he held for thirty years and followed by a three-year period as President. He remained in association with the company until his death.[br]Bibliography1919, "Heat treatment and constitution of Duralumin", Sci.

14 Stanley, Robert Crooks
[br]b. 1 August 1876 Little Falls, New Jersey, USAd. 12 February 1951 USA[br]American mining engineer and metallurgist, originator of Monel Metal[br]Robert, the son of Thomas and Ada (Crooks) Stanley, helped to finance his early training at the Stevens Institute of Technology, Hoboken, New Jersey, by working as a manual training instructor at Montclair High School. After graduating in mechanical engineering from Stevens in 1899, and as a mining engineer from the Columbia School of Mines in 1901, he accepted a two-year assignment from the S.S.White Dental Company to investigate platinum-bearing alluvial deposits in British Columbia. This introduced him to the International Nickel Company (Inco), which had been established on 29 March 1902 to amalgamate the major mining companies working the newly discovered cupro-nickel deposits at Sudbury, Ontario. Ambrose Monell, President of Inco, appointed Stanley as Assistant Superintendent of its American Nickel Works at Camden, near Philadelphia, in 1903. At the beginning of 1904 Stanley was General Superintendent of the Orford Refinery at Bayonne, New Jersey, where most of the output of the Sudbury mines was treated.Copper and nickel were separated there from the bessemerized matte by the celebrated "tops and bottoms" process introduced thirteen years previously by R.M.Thompson. It soon occurred to Stanley that such a separation was not invariably required and that, by reducing directly the mixed matte, he could obtain a natural cupronickel alloy which would be ductile, corrosion resistant, and no more expensive to produce than pure copper or nickel. His first experiment, on 30 December 1904, was completely successful. A railway wagon full of bessemerized matte, low in iron, was calcined to oxide, reduced to metal with carbon, and finally desulphurized with magnesium. Ingots cast from this alloy were successfully forged to bars which contained 68 per cent nickel, 23 per cent copper and about 1 per cent iron. The new alloy, originally named after Ambrose Monell, was soon renamed Monel to satisfy trademark requirements. A total of 300,000 ft2 (27,870 m2) of this white, corrosion-resistant alloy was used to roof the Pennsylvania Railway Station in New York, and it also found extensive applications in marine work and chemical plant. Stanley greatly increased the output of the Orford Refinery during the First World War, and shortly after becoming President of the company in 1922, he established a new Research and Development Division headed initially by A.J.Wadham and then by Paul D. Merica, who at the US Bureau of Standards had first elucidated the mechanism of age-hardening in alloys. In the mid- 1920s a nickel-ore body of unprecedented size was identified at levels between 2,000 and 3,000 ft (600 and 900 m) below the Frood Mine in Ontario. This property was owned partially by Inco and partially by the Mond Nickel Company. Efficient exploitation required the combined economic resources of both companies. They merged on 1 January 1929, when Mond became part of International Nickel. Stanley remained President of the new company until February 1949 and was Chairman from 1937 until his death.[br]Principal Honours and DistinctionsAmerican Society for Metals Gold Medal.

17 Monell, Ambrose
SUBJECT AREA: Metallurgy[br]b. 1874 New York, USAd. 2 May 1921 Beacon, New York, USA[br]American metallurgist who gave his name to a successful nickel-copper alloy.[br]After graduating from Columbia University in 1896. Monell became a metallurgical engineer to the Carnegie Steel Company, rising in six years to be Assistant to the President. In 1900, while Manager of the company's open-hearth steelworks at Pittsburg, he patented a procedure for making high-carbon steel in basic conditions on the hearth of a fixed/stationary furnace; the method was intended to refine pig-iron containing substantial proportions of phosphorus and to do so relatively quickly. The process was introduced at the Homestead Works of the Carnegie Steel Company in February 1900, where it continued in use for some years. In April 1902 Monell was among those who launched the International Nickel Company of New Jersey in order to bring together a number of existing nickel interests; he became the new company's President. In 1904–5, members of the company's metallurgical staff produced an alloy of about 70 parts nickel and 30 copper which seemed to show great commercial promise on account of its high resistance to corrosion and its good appearance. Monell agreed to the suggestion that the new alloy should be given his name; for commercial reasons it was marketed as "Monel metal". In 1917, following the entry of the USA into the First World War, Monell was commissioned Colonel in the US Army (Aviation) for overseas service, relinquishing his presidency of the International Nickel Company but remaining as a director. At the time of his death he was also a director in several other companies in the USA.[br]Bibliography1900, British patent no. 5506 (taken out by O. Imray on behalf of Monell).Monell insinuated an account of his steel-making procedure at a meeting of the Iron and Steel Institute held in London and reported in The Journal of the Iron and SteelInstitute (1900) 1:71–80; some of the comments made by other speakers, particularly B.Talbot, were adverse. The following year (1901) Monell produced a general historical review: "A summary of development in open-hearth steel", Iron TradeReview 14(14 November):39–47.Further ReadingA.J.Wadhams, 1931, "The story of the nickel industry", Metals and Alloys 2(3):166–75 (mentions Monell among many others, and includes a portrait (p. 170)).JKA -
