| 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 2.7×10-3 GPa-1 and 2.3×10-3 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. |
