Günter Petzow
Günter Petzow (born 8 July 1926 in Nordhausen, Thuringia) is a German materials scientist and former director at the Max Planck Institute for Metals Research. Biography. He studied Chemistry and Physical Metallurgy at the University of Stuttgart and the Max Planck Institute for Metals Research. He received his master's degree (Dipl.-Ing) in 1956 and finished his dissertation (Dr. rer. nat.) on "Phase Equilibria of Quarternary Metallic Systems" in 1959. Afterwards, he took over as the head of two research groups: phase diagrams of metallic systems and metallography in Stuttgart. Furthermore, he built up the Powder Metallurgical Laboratory  in Stuttgart-Büsnau as a place of interdisciplinary research, which attracted guest researchers from all over the world. As a result, the current large campus of the MPG has been established. In 1973 he was appointed scientific member of the board of directors of the Max Planck Society. He was Executive Managing Director of Max-Planck-Institute for Metals Research in Stuttgart and also Professor at the Universities of Stuttgart and Berlin, where he taught courses in equilibrium phase diagrams and powder metallurgy; he is now retired. His main scientific interests dealt with problems in the field of physical metallurgy , powder metallurgy, special ceramics and phase diagrams of metallic and ceramic materials. He is the author and co-author of more than 600 research papers, 10 books, and holds 27 patents. Some of his most important papers and publications are on phase equilibria between intermetallic compounds to the knowledge of peritectic reactions, constitution and properties of cermets, metallography, high-temperature materials, Beryllium and its compounds, liquid phase sintering, particle rearrangement, metallographic etching, toughening of ceramics, Sialon ceramics, sintering of SiN ceramics, metal-ceramic interfaces and processing of advanced ceramics. One important achievement was, by using sophisticated reinforcing mechanisms of the  originally brittle ceramic, to create a reliable "quasi-ductility" and thus operational capability for excessive mechanical and thermal loads. Prof. Petzow was President of the German Society for Materials and acts on the board of directors of several scientific societies. He was chairman of the European Action COST 507 "Measurement and Evaluation of Thermochemical and Thermophysical Properties to Provide a Database for the Development of New Light Alloys". He is the founding editor of the journal ""Practical Metallography"", was editor-in-chief of ""Zeitschrift für Metallkunde"", editor of the book series "Ternary Alloys" and member of several scientific academies and  advisory boards. In 1989, he was awarded the Skaupy Prize by the Community Committee Powder Metallurgy for outstanding achievements in the field of powder metallurgy. Petzow received seven honorary doctorates, six honorary professorships and seven honorary memberships in prestigious scientific societies. Since 1993 he has been a full member of the Academia Europaea. The ""Günter Petzow Prize"" for outstanding research is awarded to a young scientist each year at an annual summer colloquium in Stuttgart.
