Briefly:

Dr. John M. Tartaglia, a Senior Metallurgical Engineer and the former Engineering Manager at Element Wixom, has been performing failure analyses, materials characterization, heat treatment consulting, and expert witness testing for more than 40 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 an Associate Editor for two scholarly metallurgical journals (Materials and Metallurgical Transactions and Journal of Materials Engineering and Performance), chapter writer for an ASM Handbook, a Fellow of ASM International and an award-winning author for the American Foundry Society.
