Abstract

This paper reports the results of hypervelocity impact (HVI) experiments on cryogenic aluminum alloys at 122 K. Target plates were impinged by room temperature aluminum spheres at speeds ranging from 1 to 3.7 km/s in air at 10 Pa. The results were compared with HVI results at room temperature. We visualized the HVI processes by shadowgraph and recorded them with a digital high-speed video camera. We showed temperature effects of target plate physical properties on the formation of debris clouds and impact craters and hence the shielding efficiency of aluminum alloys at low temperature.
