| Abstract: | The glass transition and crystallization behavior of Zr46.75Ti8.25Cu7.5Ni10Be27.5 bulk amorphous alloy are investigated by X-ray diffraction and differential scanning calorimetry under high temperature and high pressure. The results show that the free volume and enthalpy and crystallization activation energy decrease with increasing pressure. |

| Keywords: | bulk amorphous alloy high pressure differential scanning calorimetry glass transition |
