Thermodynamic Properties of the Bulk Metallic Glass

By Differential Scanning Calorimetry (DSC), the transition temperatureTg and the primly crystallization temperatureTxof the metallic alloy Zr-106 are measured. Their values are 325℃and 470℃respectively. After the material is heated at the different temperature and different time lengths in the temperature interval ofTgand Tx, the microstructure of the as-received material is investigated by using X-ray diffraction and Transmission Electron Microscopy, meanwhile, a hot press test is carried out at a specific temperature of 370℃. The results show that the alloy has a large supercooled liquid region and high thermal stability against crystallization, and is excellent in heating plasticity.
