18 Chevenard, Pierre Antoine Jean Sylvestre
SUBJECT AREA: Metallurgy[br]b. 31 December 1888 Thizy, Rhône, Franced. 15 August 1960 Fontenoy-aux-Roses, France[br]French metallurgist, inventor of the alloys Elinvar and Platinite and of the method of strengthening nickel-chromium alloys by a precipitate ofNi3Al which provided the basis of all later super-alloy development.[br]Soon after graduating from the Ecole des Mines at St-Etienne in 1910, Chevenard joined the Société de Commentry Fourchambault et Decazeville at their steelworks at Imphy, where he remained for the whole of his career. Imphy had for some years specialized in the production of nickel steels. From this venture emerged the first austenitic nickel-chromium steel, containing 6 per cent chromium and 22–4 per cent nickel and produced commercially in 1895. Most of the alloys required by Guillaume in his search for the low-expansion alloy Invar were made at Imphy. At the Imphy Research Laboratory, established in 1911, Chevenard conducted research into the development of specialized nickel-based alloys. His first success followed from an observation that some of the ferro-nickels were free from the low-temperature brittleness exhibited by conventional steels. To satisfy the technical requirements of Georges Claude, the French cryogenic pioneer, Chevenard was then able in 1912 to develop an alloy containing 55–60 per cent nickel, 1–3 per cent manganese and 0.2–0.4 per cent carbon. This was ductile down to −190°C, at which temperature carbon steel was very brittle.By 1916 Elinvar, a nickel-iron-chromium alloy with an elastic modulus that did not vary appreciably with changes in ambient temperature, had been identified. This found extensive use in horology and instrument manufacture, and even for the production of high-quality tuning forks. Another very popular alloy was Platinite, which had the same coefficient of thermal expansion as platinum and soda glass. It was used in considerable quantities by incandescent-lamp manufacturers for lead-in wires. Other materials developed by Chevenard at this stage to satisfy the requirements of the electrical industry included resistance alloys, base-metal thermocouple combinations, magnetically soft high-permeability alloys, and nickel-aluminium permanent magnet steels of very high coercivity which greatly improved the power and reliability of car magnetos. Thermostatic bimetals of all varieties soon became an important branch of manufacture at Imphy.During the remainder of his career at Imphy, Chevenard brilliantly elaborated the work on nickel-chromium-tungsten alloys to make stronger pressure vessels for the Haber and other chemical processes. Another famous alloy that he developed, ATV, contained 35 per cent nickel and 11 per cent chromium and was free from the problem of stress-induced cracking in steam that had hitherto inhibited the development of high-power steam turbines. Between 1912 and 1917, Chevenard recognized the harmful effects of traces of carbon on this type of alloy, and in the immediate postwar years he found efficient methods of scavenging the residual carbon by controlled additions of reactive metals. This led to the development of a range of stabilized austenitic stainless steels which were free from the problems of intercrystalline corrosion and weld decay that then caused so much difficulty to the manufacturers of chemical plant.Chevenard soon concluded that only the nickel-chromium system could provide a satisfactory basis for the subsequent development of high-temperature alloys. The first published reference to the strengthening of such materials by additions of aluminium and/or titanium occurs in his UK patent of 1929. This strengthening approach was adopted in the later wartime development in Britain of the Nimonic series of alloys, all of which depended for their high-temperature strength upon the precipitated compound Ni3Al.In 1936 he was studying the effect of what is now known as "thermal fatigue", which contributes to the eventual failure of both gas and steam turbines. He then published details of equipment for assessing the susceptibility of nickel-chromium alloys to this type of breakdown by a process of repeated quenching. Around this time he began to make systematic use of the thermo-gravimetrie balance for high-temperature oxidation studies.[br]Principal Honours and DistinctionsPresident, Société de Physique.

20 Brearley, Harry
SUBJECT AREA: Metallurgy[br]b. 18 February 1871 Sheffield, Englandd. 14 July 1948 Torquay, Devon, England[br]English inventor of stainless steel.[br]Brearley was born in poor circumstances. He received little formal education and was nurtured rather in and around the works of Thomas Firth \& Sons, where his father worked in the crucible steel-melting shop. One of his first jobs was to help in their chemical laboratory where the chief chemist, James Taylor, encouraged him and helped him fit himself for a career as a steelworks chemist.In 1901 Brearley left Firth's to set up a laboratory at Kayser Ellison \& Co., but he returned to Firth's in 1904, when he was appointed Chief Chemist at their Riga works, and Works Manager the following year. In 1907 he returned to Sheffield to design and equip a research laboratory to serve both Firth's and John Brown \& Co. It was during his time as head of this laboratory that he made his celebrated discovery. In 1913, while seeking improved steels for rifle barrels, he used one containing 12.68 per cent chromium and 0.24 per cent carbon, in the hope that it would resist fouling and erosion. He tried to etch a specimen for microscopic examination but failed, from which he concluded that it would resist corrosion by, for example, the acids encountered in foods and cooking. The first knives made of this new steel were unsatisfactory and the 1914–18 war interrupted further research. But eventually the problems were overcome and Brearley's discovery led to a range of stainless steels with various compositions for domestic, medical and industrial uses, including the well-known "18–8" steel, with 18 per cent chromium and 8 per cent nickel.In 1915 Brearley left the laboratory to become Works Manager, then Technical Director, at Brown Bayley's steelworks until his retirement in 1925.[br]Principal Honours and DistinctionsIron and Steel Institute Bessemer Gold Medal 1920.BibliographyBrearley wrote several books, including: 1915 (?), with F.Ibbotson, The Analysis of Steelworks Materials, London.The Heat Treatment of Tool Steels. Ingots and Ingot Moulds.Later books include autobiographical details: 1946, Talks on Steelmaking, American Society for Metals.1941, Knotted String: Autobiography of a Steelmaker, London: Longmans, Green.Further ReadingObituary, 1948, Journal of the Iron and Steel Institute: 428–9.LRD
