Dr. John Tartaglia is a senior expert that specializes in the testing of wrought steels, aluminum and magnesium.


An expert in wrought steels, aluminum, magnesium, fatigue, failure analysis, scanning and transmission electron microscopy, and energy dispersive spectroscopy and is an experienced expert witness in failure analysis litigation. Dr. Tartaglia holds B.S. and Ph.D. degrees in Materials Engineering from Rensselaer Polytechnic Institute.

Dr. Tartaglia is a Fellow of ASM International and a member of TMS, MRS, and the ASTM metallography, mechanical testing, fatigue, and forensics committees. In 2013, he was awarded the American Foundry Society 2013 Howard F. Taylor Award for his paper examining a strain-life fatigue database for cast irons, which he developed using funding from the AFS and the United States Department of Energy (DoE).
