Graduate Research Associate – Dean Sage
Biographical Sketch
Dean Sage is a second year PhD student in the Welding Engineering program at The Ohio State University. His undergraduate career consists of B.S. degrees in Biological Engineering as well as Materials Engineering with a specialty in metals processing from the University of Florida. His research experience covers failure analysis and fracture mechanics of nickel-based gas turbine components.
Graduate Research
Dean’s graduate research project focuses on identifying the fundamental mechanism behind liquid metal embrittlement (LME) in the Fe-Zn and Fe-Cu systems. He is currently working on the effect of microstructural features (e.g. grain size, grain boundary character) on crack initiation and propagation in 304 stainless steel. For this work he received a Kickstarter Grant from the Institute of Materials Research (IMR) at The Ohio State University.
