| 摘 要： | 利用二级轻气炮研究了在平面冲击波高速撞击下，Zr41Ti14Cu12.5Ni10Be22.5大块非晶合金的损伤与断裂行为。实验结果表明：在高速冲击压缩下，大块非晶合金断裂面的角度小于通常压缩情况的角度，这是由高速撞击下材料极高的应变速率决定的；极高的应变速率变形和局域绝热剪切加热造成局部熔化；在温度和压力的共同作用下，非晶合金发生晶化现象。

| Abstract: | Planar shock compression effects on damage and cracking in Zr41 Ti14 Cu12.5 Ni10 Be22.5 bulk amorphous alloy are studied using a two-stage light gas gun. The experimental result indicates that the cracking angel 8 of bulk amorphous alloy under planar shock compression is smaller than that of traditional compression experiment, it is decided by the highest strain velocity under shock compression conditions in bulk amorphous alloy;part of bulk amorphous alloy surface also is melt by the effects of highest strain velocity and the energy of partial adiabatic shear bands;the crystallization happens in bulk amorphous alloy by the effects of temperature and pressure. |
