"Looking at the microstructure of crystalline materials through experimentation, their properties impact performance in every modern industry."

Sean R. Agnew, Professor of Materials Science and Engineering

Our research is focused primarily on metals analysis, including magnesium alloy formability, intermetallic behaviors, and aluminum alloy fatigue. Our methods of analysis typically include uses of SEM, TEM, XRD, and Neutron diffraction. Also included in our army of techniques is mechanical testing.
