HIGHL IGHTS A D V A N C E D M A T E R I A L S & P R O C E S S E S | M A Y / J U N E 2 0 2 0 7 8 IN MEMORIAM Erhard Hornbogen, FASM, who was born in Greiz, Germany, died on April 16 at age 90. He stud- ied metal physics at the University of Clausthal, where he worked on his Ph.D. thesis and was the first to discover the shape memory effect in Cu-based alloys in 1956. Later he worked at the Max Planck Institute for Metals Research in Stuttgart, where he tackled the effect of lattice defects on nucleation events in solids. His work applied new TEMmethods to study particle strengthened alloys. This led to the understanding and design of superalloys that are the basis for modern aircraft engines. He was a professor for metal physics at the University of Goettingen, 1965-1967. Hornbogen founded the Insti- tute for Materials at Ruhr-University Bochum, where he was chair of materials science, 1968-1995. His studies provided the basis for understanding the structures and properties of grain boundaries in metals. Hornbogen was an elected member of the North Rhine-Westphalia Academy of Sciences and of the German Academy of Technical Sciences. He was also the recipient of the TMS Mehl Award, honorary membership of the Japanese Institute for Materials, and an honorary doctorate from the University of Miskolc. Kent L. Johnson, FASM, died on April 4 in Raleigh, N.C., at age 79. He was a well-respected con- sultant with an expertise in metallurgical failure analysis and was president and founder of Materials Consulting & Engineering Ltd. He received his B.S. and Ph.D. in metallurgical engineering from the Illinois Institute of Technology in 1965 and 1972, respectively, and was a licensed Professional Engi- neer in Illinois, Arkansas, and Wisconsin. He was a frequent instructor with ASM International and the American Welding Society, having previously been a part-time faculty in metallurgy at the Illinois Institute of Technology in Chicago. Johnson specialized in investigative evaluations while working with numerous Illinois companies including Engineering Systems Inc. in Aurora, Bodycote Materials Testing Group in Skokie, and Parker Engineering Inc. in Naperville, among others. He became an ASM Fellow in 2006 and was cited “for pioneering leadership and significant contributions in advanced welding metallurgy and flexible manufacturing automation technologies including flaw detection/failure analysis in pres- sure containment vessels.” Johnson served as chair of the ASMHandbook Committee 2008-2010 and was a member of the Committee starting in 1999. He also frequently served as a peer reviewer. Johnson was a member of the Chicago Regional Chapter and past chair of the previous Chicago Western Chapter. Bozidar Liscic, FASM, passed away on April 19 at age 91. Liscic was a full professor of mechani- cal engineering at the University of Zagreb in Croatia, 1982-1999, and amember of the Croatian Acad- emy of Science and Art since 1997. He served as president of the International Federation for Heat Treatment and Surface Engineering (IFHTSE), 2004-2005. Liscic was well known globally, serving as a visiting professor at the University of Cincinnati and as expert for heat treatment for the United Nations Development Programme and International Labor Organization. Liscic made numerous vital and lasting contributions to the fundamental understanding of quenching and heat treating technol- ogy. Much of his work has been memorialized in “Theory and Technology of Quenching,” an author- itative handbook co-edited by B. Liscic, H.M. Tensi, and W. Luty. Liscic was the long-time chairman of the IFHTSE Quenching and Cooling Committee from 1977 until his retirement. He was elected as a Fellow of ASM International and IFHTSE. The International Conference on Quenching and Control of Distortion in Honor of Professors Bozidar Liscic and Hans M. Tensi was held in Indianapolis in 2001. George T. Murray, 93, died on March 22, in Pacific Palisades, Calif. He was a professor of mate- rials engineering at Cal Poly San Luis Obispo and served as chair of the department, retiring in 1993. Murray graduated as valedictorian from his high school at the age of 16 and entered Eastern State Teachers College in Richmond, Ky., as a math/physics major, after scoring in the top one percent on the state mathematics exam. In 1944, Murray transferred to the University of Kentucky (UK) to pursue a degree in engineering. After two years in the Navy, he returned to UK and received his B.S. in metallurgical engineering. He later received an M.S. from the University of Tennessee and a Ph.D. from Columbia University. Murray co-founded Materials Research Corp., where he served as director of research and later corporate vice president. In 1978, he started a second career at Cal Poly. Murray authored “Introduction to Engineering Materials” by CRC Press, as well as an ASM Handbook Volume 2 article, “Preparation and Characterization of Pure Metals.” Hornbogen Johnson Liscic Murray IN MEMORIAM
