  • Reverse impact experiments were performed at a shock pressure range from 30 GPa to 73 GPa to investigate the dynamic response of magnesium aluminum alloy. A displacement interferometer system for any reflector was employed to measure the impact velocity and sample/window interface particle velocities. The Hugoniot data obtained in this study had a good agreement with the data published before, however, the sound velocities extracted from our experiments showed a transition from longitudinal to bulk sound velocity. This discontinuity is attributed to melting transition under shock compression, and the transition pressure range is estimated from 40 GPa to 57 GPa.
