Wolfgang Pitsch

from Wikipedia, the free encyclopedia

Wolfgang Pitsch (born August 28, 1927 ; † May 30, 2019 in Dinslaken ) was a German physicist , materials scientist and university professor .

Life

Pitsch studied at the University of Göttingen , where he received his doctorate in natural sciences in 1954 with his dissertation on experimental and theoretical investigations of α- iron as a function of the carbon content .

Pitsch then became a research associate at the Max Planck Institute for Iron Research . In 1957 he became a member of the electron microscopy group headed by Angelica Schrader . Pitsch became known through his studies of the orientation relationships in phase transformations and precipitation processes in iron-carbon alloys . One research focus was the martensite transformation in the iron-carbon system . There he found another orientation relationship that now bears his name. In 1962 Pitsch received the Masing Prize from the German Society for Material Science . In 1967 he completed his habilitation at RWTH Aachen University with his habilitation thesis on the crystallographic analysis of phase transformations in metals . He then always gave a lecture at the RWTH Aachen. In 1969 he became head of the metal physics group at the Max Planck Institute for Iron Research.

In 1971 Pitsch was appointed Scientific Member of the Max Planck Society and Head of Department at the Max Planck Institute for Iron Research. Its wide field of work included not only the phase transformations and precipitation processes necessary for the precipitation are important to the formation of superstructures (long-range order) in substitution solid solutions and the effects of external forces ( magnetic , mechanical stresses ) on precipitation processes. Together with others, Pitsch created the Material Science Handbook , in which he designed the basic chapter on the structure of steels.

In 1994 the German Society for Material Science made Pitsch an honorary member.
