Dr. Nicholas E Nanninga joined Secat in 2020 as Technical Director. Nick’s responsibilities at Secat include interfacing with new customers, coordinating R&D projects with universities and government agencies, supporting the development of technical training courses, and assisting in maintaining our quality systems.
Prior to joining Secat, Dr. Nanninga was Corporate Director of Materials and Processes at Accuride Corporation. At Accuride, Nick managed a Materials lab that supported several North American facilities through materials testing and analysis, alloy development, and process R&D. During his time at Accuride, Nick developed a new alloy and forging process for manufacturing aluminum wheels. These patented technological advances resulted in a 15 % reduction in the weight of an industry standard commercial vehicle wheel.
Before Accuride, Dr. Nanninga spent two years at Timet Corporation, where he worked on developing novel titanium alloys and manufacturing processes. Nick started his career as a post-doc for the National Institute of Standards and Technology (NIST). At NIST, Nick was responsible for researching the effects of high-pressure hydrogen gas on the mechanical properties of metals, specifically those proposed for use in a “hydrogen economy”. To this end, Dr. Nanninga and his colleagues designed, built, and instrumented a safe facility for conducting mechanical tests inside a high-pressure hydrogen gas chamber.
Dr. Nanninga received his B.S., M.S. and Ph.D. degrees in Materials Science and Engineering from Michigan Technological University in 2003, 2005, and 2008, respectively. Dr. Nanninga’s M.S. thesis focused on hydrogen embrittlement in steel fasteners used in the automotive industry. During his Ph.D., he investigated the high cycle fatigue behavior of AA6XXX aluminum extrusions, with specific emphasis on the effects of seam welds, charge welds, and die lines on fatigue properties.
Dr. Xiao has been at Secat, Inc. for 19 years. He serves as the Technical Manager and supervises the lab and most technical matters. His strong background in physical metallurgy and failure analysis of aluminum serves him well to guide and support technical personnel.
Dr. Xiao received his doctorate in metallurgical engineering from University of Tennessee at Knoxville. He has more than 30 years of industrial and academic research and development experience. He possesses strong hands-on problem solving skills in metal casting, welding, heat-treatment, materials processing development, failure analysis and materials characterization utilizing various modern analytical techniques and instruments.
Dr. Xiyu Wen is a Senior Research Associate for the Center for Aluminum Technology. He was a 1983 graduate of the Jilin University in P. R. China with a B.S. in Physics. He was a faculty member for three years at the Northeast Heavy Machinery Institute, P. R. China. In 1989, Dr Wen obtained M. S. in Materials Science from Yanshan University in P.R. China, where he worked again in Teaching and Research in Materials Science. Dr. Wen received his PhD degree from The Hong Kong Polytechnic University in 2000.
His research works focus on the physical and mechanical metallurgy mainly concerned with textures and microstructures of metal materials/sheet metal forming.
Dr. Wilson Xu joined Secat in June 2018 as a Senior Materials Engineer. Wilson’s work here is on metallurgical analysis and failure analysis of various metal parts and products.
Wilson has worked in materials engineering for more than 20 years. During past two decades he has mainly worked as an engineer in casting and heat treatment of light weight metals, fabrication of metal matrix composites, characterization of microstructures and nanostructures in various materials, relationships between physical, electrochemical, and mechanical properties and the microstructures of light weight metals. Wilson has authored or co-authored more than 100 publications on peer reviewed journals.
Yan Jin, Ph.D., joined Secat as a Materials Engineer in December 2018. His work at Secat primarily relates to billet evaluation, including 6000 and 7000 series of aluminum alloys, failure analysis and evaluation on a series of aluminum products in forms of casting, forging, extrusion and rolling, etc., and materials characterization using Electron Microscopy techniques at UK Electron Microscopy Center (EMC).
He majored Materials Science and Engineering during his undergraduate and graduate studies, respectively. In 2016, he obtained Ph.D. degree in Materials Science and Engineering from University of Kentucky (UK) with focus on the effects of microstructure and microtexture on multi-site fatigue crack nucleation of high strength aluminum alloys. After completing his Ph.D., he worked in a R&D project sponsored by General Motors as a Postdoctoral Scholar at UK, focusing on developing and validating a scratch adhesion test method for thermal sprayed coating on die casting aluminum alloys. Prior to joining Secat, Dr. Jin worked at X-wave Innovations, Inc. as a Research and Development Engineer with emphasis on materials microstructure characterization and mechanical properties evaluation of additive manufactured lightweight alloys, such as Ti64 and Ni-based superalloys.
