25 Bosch, Carl
SUBJECT AREA: Chemical technology[br]b. 27 August 1874 Cologne, Germanyd. 26 April 1940 Heidelberg, Germany[br]German industrial chemist who developed the industrial synthesis of ammonia.[br]Bosch spent a year as a metalworker before studying chemistry at Leipzig University, obtaining his doctorate in 1898. The following year, he entered Badische Soda-, Anilin Fabrik (BASF), the leading German manufacturer of dyestuflfs. Between 1902 and 1907 he spent much time investigating processes for nitrogen fixation. In 1908 Fritz Haber told BASF of his laboratory-scale synthesis of ammonia from its constituent elements, and in the following year Bosch was assigned to developing it to the industrial scale. Leading a large team of chemists and engineers, Bosch designed the massive pressure converter and other features of the process and was the first to use the water gas shift reaction to produce the large quantities of hydrogen that were required. By 1913 Bosch had completed the largest chemical engineering plant at BASF's works at Oppau, and soon it was producing 36,000 tons of ammonium sulphate a year. Bosch enlarged the Oppau plant and went on to construct a larger plant at Leuna.In 1914 Bosch was appointed a Director of BASF. At the end of the First World War he became Technical Adviser to the German delegation at the peace conference. During the 1920s BASF returned to its position of pre-eminence in high-pressure technology, thanks largely to Bosch's leadership. Although increasingly absorbed in administrative matters, Bosch was able to support the synthesis of methane and the hydrogenation of coal tar and lignite to make petrol. In 1925 BASF merged with other companies to form the giant IG Farbenindustrie AG, of which Bosch became Chairman of the Managing Board. His achievements received international recognition in 1931 when he was awarded, with F. Bergius, the Nobel Prize in Chemistry for high-pressure synthesis.[br]Bibliography1932, Über die Entwicklung der chemischen Hochdruckindustrie bei der Aufbau der neuen Ammoniakindustrie.Further ReadingK.Holdermann, 1953, Carl Bosch, Leben und Werk.See also biographical memoir in Chemische Berichte 190 (1957), pp. xix–xxxix.LRD -
26 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. Commandeur de la Légion d'honneur.Bibliography1929, Analyse dilatométrique des matériaux, with a preface be C.E.Guillaume, Paris: Dunod (still regarded as the definitive work on this subject).The Dictionary of Scientific Biography lists around thirty of his more important publications between 1914 and 1943.Further Reading"Chevenard, a great French metallurgist", 1960, Acier Fins (Spec.) 36:92–100.L.Valluz, 1961, "Notice sur les travaux de Pierre Chevenard, 1888–1960", Paris: Institut de France, Académie des Sciences.ASDBiographical history of technology > Chevenard, Pierre Antoine Jean Sylvestre
