Willy Oelsen

from Wikipedia, the free encyclopedia

Willy Oelsen (born September 11, 1905 in Ostheim before the Rhön ; † July 25, 1970 in Ratingen - Hösel ) was a German metalworker and metallurgist .

Life

Willy Oelsen, son of the railway conductor Friedrich Oelsen (* 1874) and his wife Ida geb. Barthelmes (* 1882), after graduating from high school in 1924 in Göttingen , studied chemistry , mathematics , physics , mineralogy and metal science at the University of Göttingen from 1925 . Under Gustav Tammann , he completed his dissertation The Dependence of the Concentration of Saturated Mixed Crystals on Temperature , with which he was awarded a Dr. phil. received his doctorate. He then studied the reactions between metal baths and slags as Tammann's assistant in his institute for physical chemistry .

In 1931 he became personal assistant to the institute director Friedrich Körber of the Kaiser Wilhelm Institute for Iron Research in Düsseldorf , in order to take over the management of the chemical and metallurgical department after a few years . In 1941 he was appointed a scientific member of the institute. His research contributed significantly to the clarification of the metallurgical basis of the Thomas process .

Oelsen taught from 1938 as a lecturer and from 1944 as an adjunct professor of metal chemistry at the University of Münster and during the last years of the war at the Clausthal mining academy , where the Düsseldorf Kaiser Wilhelm Institute for iron research was relocated in 1943 after the bombing. In 1948 Oelsen was appointed to the Chair of Metallurgy and Foundry at the Clausthal Mining Academy, where the development of high-temperature calorimetry for the systematic measurement of the heat of formation of intermetallic compounds and entire series of alloys as well as the coulombimetric analysis of carbon and sulfur in iron alloys and slags in particular became the focus of his work. For four years he was dean of the Faculty of Mining and Metallurgy and in 1958/59 Rector of the Bergakademie.

In 1959 he returned to Düsseldorf with the appointment of director of the iron research institute, which had become the Max Planck Institute for Iron Research and which he headed until his death. Extensive investigations into the reactions between carbon-saturated iron melts and slag formed the focus of his work. His over 140 publications have found worldwide recognition.
