Dr. S. Lee Semiatin, a member of the scientific and professional cadre of senior executives, is a senior scientist in materials processing and processing science, and research leader of the Processing Science Group, Materials and Manufacturing Directorate, Air Force Research Laboratory, Wright-Patterson Air Force Base, Ohio. In this position, he is responsible for formulating and leading the Air Force research and development program in processing metals and composites. He assists other AFRL directorates and Air Force system program offices in solving different processing problems for aircraft and space systems.
Semiatin worked at Battelle Memorial Institute from 1978 to 1991 prior to joining the Air Force. At Battelle he conducted and directed assorted processing-related programs for many government and industrial clients. Much of his government-sponsored work was for the Air Force Materials Laboratory and the Air Force Office of Scientific Research. This included basic studies on flow localization phenomena in various aerospace alloys and the fundamentals of material behavior during deformation processing. Programs for industrial clients focused heavily on developing new products and processes for numerous conventional and advanced alloys for the automotive, appliance, aerospace and other industries. In June 1991 Semiatin joined the Materials Directorate as senior scientist in the Metals, Ceramics and Nondestructive Evaluation Division, and as research leader of the Processing Science Group. Under his direction, the group conducts basic and applied research and development in four major areas related to processing: advanced metallic and intermetallic alloys; composites and graded materials; conventional titanium, nickel and aluminum alloys, and novel processes. This work has led to developing various new forging, extrusion and rapid heat treatment processes, some being utilized on a production basis. In addition he consults regularly with many manufacturing vendors on material processing problems which affect Air Force systems.
Since 1991 Semiatin has also been an adjunct professor in the industrial, welding and systems engineering department at The Ohio State University where he has advised numerous graduate-level and doctoral program students in their thesis research, often on important Air Force topics. Semiatin is the author and co-author of more than 140 technical papers, 20 limited-distribution reports and three books. He has edited a variety of handbooks and conference proceedings. In addition, he holds seven U.S. patents related to processing.
