Dr. Murray specializes in failure analysis and failure prevention of engineering materials, components, and systems. His specific expertise includes metallurgy, microstructure evolution, additive manufacturing, and high temperature materials testing.
Dr. Murray assists clients in understanding the underlying factors that have resulted in failed, fractured, and corroded components and systems, and how to make progress in preventing these failures from occurring in the future. This experience has consisted of direct-cause failure analysis of components to interdisciplinary investigations of engineering systems. His recent project experience includes failure analysis of fractured leaf-springs, railroad fastening equipment, solar panel junction boxes, leaking brazed joints, steel bolt fatigue failures, nitinol medical devices, sprinkler coating corrosion, and candidate alloy reviews. Dr. Murray has also supported clients in domestic litigation and international arbitration disputes.
Dr. Murray has an extensive background in materials characterization using a variety of analytical tools and techniques including metallography, electron microscopy, mechanical testing, CALPHAD modeling, differential thermal analysis, and oxidation testing.
Prior to joining Exponent, Dr. Murray was a Graduate Researcher at the University of California, Santa Barbara, where he received his Ph.D. in 2021. While there, he studied the high temperature properties of a novel class of precipitation strengthened CoNi-base superalloys. After identifying alloy compositions with promising high temperature properties, these alloys were demonstrated to be processible through additive manufacturing techniques such as selective laser melting and electron beam melting with low defect content. This is currently challenging for commonly used high strength Ni-base superalloys due to their susceptibility to cracking during additive manufacturing. This work involved grain-scale and precipitate-scale microstructural evaluation, microsegregation measurements, solidification modeling, and heat treatment development.
