MEMBRE D’HONNEUR 2019

S. Lee SEMIATIN

Dr. Lee Semiatin is Senior Scientist (emeritus) for materials processing and processing science in the Air Force Research Laboratory, Materials and Manufacturing Directorate. He received a BES in Engineering Mechanics from Johns Hopkins University (1971) and PhD in Metallurgy and Materials Science from Carnegie Mellon University (1977).

Dr. Semiatin worked at Battelle Memorial Institute from 1978 to 1991. Here, he performed and directed research programs for a wide range of government and industry clients. His basic research resulted in new insights into the workability of difficult-to-process aerospace alloys and methods to fabricate such materials to enhance microstructure evolution and subsequent service properties. Applied research projects included the development and implementation of novel or improved processes for a variety of automotive, appliance, and aerospace applications.

In 1991, Dr. Semiatin joined the Materials Directorate as Senior Scientist in the Metals and Ceramics Division and Research Leader, Metals Processing. Under his direction, R&D was conducted in four major areas: conventional titanium, nickel, and aluminum alloys; advanced metallic, intermetallic, and nanocrystalline alloys; novel processes; and advanced modeling tools for the prediction of microstructure, texture, and damage evolution during deformation, solidification, or vapor-phase processing. The synthesis of various modeling, characterization, and input-data tools that underlie Integrated Computational Materials Engineering have formed a key part of this research. These efforts have led to the development of various new forging, extrusion, and rapid heat treatment processes, a number of which are utilized on a production basis. In addition, he consults regularly with a number of manufacturing companies on material-processing problems. He is also Adjunct Professor at the Ohio State University, the University of Dayton, and Wright-State University, at which he advises MS and PhD students on their thesis research.

Dr. Semiatin has authored/co-authored over 450 journal papers and 30 limited distribution reports in the area of materials processing. He has also written/edited 18 books/handbooks/conference proceedings and holds 9 US patents.

Dr. Semiatin has been elected Fellow of ASM International (1992), the Air Force Research Laboratory (1993), and the Minerals, Metals, Materials Society (TMS) (2008), as well as Member, National Academy of Engineering (2019). Other recognitions include an honorary ScD degree from the Institute for Metal Physics of the National Academy of Sciences of Ukraine (2002), Presidential Rank Meritorious Senior Professional Award (2007). ASM Gold Medal (2007), TMS Bruce Chalmers Award (2017), and ASM Albert Sauveur Award (2018).
