Professor
Mechanical Engineering & Materials Science and Engineering
About
Dr. Hartwig received his Ph.D. in metallurgical engineering from the University of Wisconsin-Madison in 1977 and has been at Texas A&M since 1986. He received a Texas A&M Engineering Excellence Grant in 1987, and an Outstanding Graduate Teaching Award in 2008. His research interests include development of better materials (nanostructured, for low temperature use, superconductors, aluminum, normal electrical conductors, and advanced structural materials and consolidation of advanced particulates); structure-property-processing relationships; sever plastic deformation of materials via equal channel angular extrusion (ECAE); applied superconductivity (composite superconductor design)
