摘要

利用二级轻气炮驱动飞片高速撞击产生的高温高压对ZrTiCuNiBe合金试样进行冲击波淬火

制备了Zr41Ti14Cu12.5Ni10Be22.5大块金属玻璃。由于冲击波对合金熔体的复杂效应

冲击波淬火制备的试样具有与水淬试样不同的结构、热稳定性和物性参数。与水淬试样相比

冲击波淬火的试样具有较高的玻璃转变温度和晶化温度

较低的密度和较高的声速。冲击波淬火是一种极具前途的大块金属玻璃制备方法。

22.5 bulky metallic glass （BMG） was prepared by shock-wave quenching generated from high temperature and high pressure by high speed impaction of driving flying plate using double-level light artillery. The prepared BMG samples are different in structure

thermal stability and properties compared with that of prepared alloy samples by water-quenching due to the comprehensive effects of shock-wave on molten alloy

having higher glass transition temperature and crystallization temperature

lower density and higher acoustic speed

which shows that shock-wave quenching is a promising method for preparation of BMG.
