Abstract The shock-induced reaction behavior of ZrCuNiAl bulk metallic glass (BMG) was investigated by means of a modified quasi-sealed test chamber. A series of quasi-sealed chamber impact experiments were conducted through launching ZrCuNiAl BMG fragments into the test chamber. It was shown that the semi-sphere shape of the modified quasi-sealed chamber suits the expanding manner of reactions. The results demonstrated that the BMG fragments 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 overpressure inside the chamber and the released chemical energy was derived to analyze the effect quantitatively.

Zr基金属玻璃冲击诱发反应特性研究

摘要 通过改进的准密封试验箱研究了ZrCuNiAl块状金属玻璃(BMG)的冲击诱导反应行为。通过将 ZrCuNiAl BMG 碎片发射到测试室中，进行了一系列准密封室冲击实验。结果表明，改进后的准密封室的半球形状适合反应的扩展方式。结果表明，BMG 碎片在撞击到钢靶上时发生了化学反应。反应释放的能量导致准密封腔室内的压力显着升高。结果表明，能量随着冲击速度的增加而增加。推导出腔室内的超压与释放的化学能之间的关系以定量分析该效应。
