摘要：

An Al/Ni composite was produced via accumulative roll-bonding (ARB) process up to four cycles. The shock-induced reaction behavior of the material was investigated by means of a quasi-sealed test chamber. The results demonstrated that the Al/Ni composite fabricated by ARE underwent chemical reaction when impacted onto steel target. The energy released by reaction led to significant pressure rise inside the quasi-sealed chamber. It was shown that the amount of energy increased with the increasing of impact velocity. A relationship between the pressure inside the chamber and the impact velocity was derived to analyze the effect quantitatively. The results of this study represented the potential of Al/Ni composite processed by ARB as reactive fragments. (C) 2016 Elsevier Ltd. All rights reserved.
