Briefly:

Dr. John M. Tartaglia, a Senior Metallurgical Engineer and the Engineering Manager at Element Wixom, has been performing failure analyses and materials characterization for more than 30 years. He holds B.S. and Ph.D. degrees in Materials Engineering from Rensselaer Polytechnic Institute (RPI) in Troy, New York. Tartaglia’s doctoral thesis concerned the elevated temperature fatigue behavior of superalloys, and he is an expert in mechanical testing, wrought steels, aluminum, magnesium, fatigue, failure analysis, scanning and transmission electron microscopy, and energy dispersive spectroscopy.

Dr. Tartaglia is a Key Reader for Materials and Metallurgical Transactions, a member of the editorial committee for Journal of Materials Engineering and Performance, chapter writer for an ASM Handbook, a member of several ASTM committees, a Fellow of ASM International and an award-winning author for the American Foundry Society.
