摘要: 本文采用金刚石对顶压砧高压装置和高压X射线技术测定了两种金属玻璃线压缩率曲线;得到Cu30Zr70和Cu25Zr75的线压缩率分别为2.710-3 GPa-1和2.310-3 GPa-1,实验最高压力超过30 GPa。实验过程中首次观察到Cu-Zr金属玻璃在室温下加压发生晶化的现象。Abstract: The determination of the compressibilities of metallic glasses Cu100-xZrx in a diamond anvil cell by the X-ray diffraction technique is described in this paper. The line compressibilities determined for Cu30Zr70 and Cu25Zr75 are 2.710-3 GPa-1 and 2.310-3 GPa-1 respectively. The highest experimental pressure is over 30 GPa. The pressure-induced crystallization of metallic glasses Cu100-xZrx at room temperature was firstly observed in this experiment.
