Shock Behavior of Galfenol

A series of shock loading experiments were conducted on Galfenol (Fe$_{\mathrm{81.6}}$Ga$_{\mathrm{18.4}})$, a magnetostrictive iron-gallium alloy developed by the NSWCCD. Flyer plate experiments were performed on the material to generate HEL and spall data via VISAR wave profiles. A larger diameter plate was added to the targets along with PDV diagnostics to determine impact times in order to come up with an estimate for the hugoniot.
