Dr. Andrzej Wojcieszynski is an esteemed Senior Consultant on Powder Metallurgy. Prior to Wingens LLC, he has been the Senior Principal Engineer at ATI Powder Metals in Pittsburgh, PA. Andrzej specializes in powder metallurgy, gas atomization, and high-performance alloys for various demanding applications, including iron-base, nickel-base, and titanium-base alloys. Dr. Wojcieszynski has made significant contributions to the field, including the invention of super high-speed steel called CPM Rex 121, which bridged the property gap between solid carbides and commercially available high-speed steels. This material became a material of choice for metal cutting tolling applications in the automotive industry in the early 2000s due to its high hardness and wear resistance capability.
Furthermore, Dr. Wojcieszynski is also a co-inventor of a nickel-base alloy with improved wear resistance for combustion engine exhaust valves, which was awarded the PACE award in 2008 for being one of the most significant developments in the automotive industry that year. His research on the effects of second-phase particle spacing and grain size on fracture toughness led to the improvement of fracture toughness in ultra-high-strength secondary hardening steels. Dr. Wojcieszynski’s research on the gas atomization process resulted in the design of a new gas delivery assembly that enabled more efficient energy transfer between the atomizing gas and the liquid metal and increased the yield of fine powder size fractions.
Dr. Wojcieszynski graduated with distinction from the University of Science and Technology in Krakow, Poland, and obtained his Ph.D. degree in Materials Science and Engineering from Carnegie Mellon University in 1993. He is also a Fellow of ASM International. Prior to his current position, Dr. Wojcieszynski taught undergraduate classes in physical metallurgy, phase diagrams, crystallography, phase transformations in steels, and heat treatment while conducting research on the effects of carbide segregation on the properties and performance of bearing steels at the Department of Physical Metallurgy at AGH Science and Technology University in Krakow.
After receiving his Ph.D., Dr. Wojcieszynski joined the Materials Science and Engineering Department at Carnegie Mellon University as a Research Associate. Later, he accepted a Research Engineer position at the Research Center of Crucible Materials Corporation in Pittsburgh, where he was responsible for alloy development, gas atomization, powder processing improvements, and technical support to the production. In 2003, he was named the Technical Director of the Tool, Valve, and Stainless Steels Section, where he led a group of engineers responsible for alloy development, gas atomization, and powder processing improvements, divisions and external customers. He continued in this position with ATI after 2009 when Crucible Research was acquired by Allegheny Technologies, Inc. and became ATI Powder Metals. Andrzej is an inventor or co-inventor of six U.S. patents concerned with high-speed steels, cold work and hot work tool steels, valve alloys, wear and corrosion-resistant tool steels, and Ni-base alloys.
Andrzej has always been an active member of the professional societies. He is a Fellow of ASM International and a Vice Chair of the ASM MS&T Programming Committee. In the past, he has been a Chairman of the ASM Pittsburgh Chapter and Chairman of the Processing and Application Sub-Committee. He is also a member of TMS, ASTM – F42 AM Committee, SAE – AMS AM Committee, and a Key Reader for Metallurgical Transactions. He also has been serving on the Board of Directors of the Polish Cultural Council in Pittsburgh since 2011.
