Measurement of post-shock temperatures in aluminum and stainless steel

Until recently experimental measurements of post-impact temperatures have been obtained only for metals at high pressures. Our aim has been to develop a technique for measuring post-shock temperatures in a variety of materials, including metals and silicates, at pressures in the range of 5 to 50 GPa, providing further insight into the shock process in these substances and additional constraints to available equation of state data. This paper describes the method we have developed, and its application to the determination of post-shock temperatures in aluminum-2024 and stainless steel-304.
