17 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.

18 Haynes, Elwood
[br]b. 14 October 1857 Portland, Indiana, USAd. 13 April 1925 Kokomo, Indiana, USA[br]American inventor ofStellite cobalt-based alloys, early motor-car manufacturer and pioneer in stainless steels.[br]From his early years, Haynes was a practising Presbyterian and an active prohibitionist. He graduated in 1881 at Worcester, Massachusetts, and a spell of teaching in his home town was interrupted in 1884–5 while he attended the Johns Hopkins University in Baltimore. In 1886 he became permanently diverted by the discovery of natural gas in Portland. He was soon appointed Superintendent of the local gas undertaking, and then in 1890 he was hired by the Indiana Natural Gas \& Oil Company. While continuing his gas-company employment until 1901, Haynes conducted numerous metallurgical experiments. He also designed an automobile: this led to the establishment of the Haynes- Apperson Company at Kokomo as one of the earliest motor-car makers in North America. From 1905 the firm traded as the Haynes Automobile Company, and before its bankruptcy in 1924 it produced more than 50,000 cars. After 1905, Haynes found the first "Stellite" alloys of cobalt and chromium, and in 1910 he was publicizing the patented material. He then discovered the valuable hardening effect of tungsten, and in 1912 began applying the "improved" Stellite to cutting tools. Three years later, the Haynes Stellite Company was incorporated, with Haynes as President, to work the patents. It was largely from this source that Haynes became a millionaire in 1920. In April 1912, Haynes's attempt to patent the use of chromium with iron to render the product rustless was unsuccessful. However, he re-applied for a US patent on 12 March 1915 and, although this was initially rejected, he persevered and finally obtained recognition of his modified claim. The American Stainless Steel Company licensed the patents of Brearley and Haynes jointly in the USA until the 1930s.[br]Principal Honours and DistinctionsJohn Scott Medal 1919 (awarded for useful inventions).BibliographyHaynes was the author of more than twenty published papers and articles, among them: 1907, "Materials for automobiles", Proceedings of the American Society of MechanicalEngineers 29:1,597–606; 1910, "Alloys of nickel and cobalt with chromium", Journal of Industrial Engineeringand Chemistry 2:397–401; 1912–13, "Alloys of cobalt with chromium and other metals", Transactions of the American Institute of 'Mining Engineers 44:249–55;1919–20, "Stellite and stainless steel", Proceedings of the Engineering Society of WestPennsylvania 35:467–74.1 April 1919, US patent no. 1,299,404 (stainless steel).The four US patents worked by the Haynes Stellite Company were: 17 December 1907, patent no. 873,745.1 April 1913, patent no. 1,057,423.1 April 1913, patent no. 1,057, 828.17 August 1915, patent no. 1,150, 113.Further ReadingR.D.Gray, 1979, Alloys and Automobiles.
