Richard Kieffer

from Wikipedia, the free encyclopedia

Richard Andreas Kieffer (born April 9, 1905 in Offenbach am Main , † March 14, 1983 in Santiago de Chile ) was a powder metallurgist and hard metal specialist.

Life

Kieffer studied chemistry from 1923 to 1928 in Freiburg im Breisgau and Frankfurt am Main, among others with Alfred Magnus (* 1880; † October 26, 1960) and Adolf Sieverts . After completing his doctorate with the thesis on the adsorption of carbon dioxide and ammonia on silica gel to the Dr. phil. nat. he worked briefly as a university assistant in Frankfurt at Lorenz and Hahn and at the Bavarian metal works in Dachau .

In 1930 he switched to Metallwerke Plansee AG in Reutte, Tyrol , as a technical and scientific employee of the company's founder Paul Schwarzkopf . Here he worked for almost 30 years on the development of hard metals and the production of new sintered materials, together with Gustav Hüttig and Hans Nowotny , among others . He developed new manufacturing processes such as arc and vacuum melting as well as the large-scale metallurgy of high-melting metals. After the annexation of Austria, the plant was under Walter Rohland . In April 1939 Werner Hotop (* 1907) joined the research institute as director. Under SS Brigade Leader Walther Schieber , Kieffer advanced to head of the special ring for sintered iron and under Karl Saur to head of the main working committee for ammunition parts from sintered iron .

In 1960 the University of Vienna appointed him honorary professor and in 1964 he was appointed to the Technical University of Vienna. Around 1967 he went on a safari in Africa. In addition to six monographs, he published 125 specialist articles. Werner Köster (1896–1989) suggested powder metallurgy and sintered materials (1943).
