摘要：
The newly designed Ti-based bulk metallic glass (BMG) in which case of fracture behavior was observed 1990MPa to compressive strength with a wide plastic deformation around 7% after process of elastic deformation. This phenomenon can be compared with those of Ti-based alloys and other Ti- based BMGs and indicates high potential to be applied in use. It was evaluated the Ti- based BMG for thermal stability that the reduced glass parameters,Delta T-x, T-rg and gamma, are 79K, 0.50 and 0.38, respectively. In addition, it reveals high activation energies for crystallization in which are estimated to E-x1 = 291.77 +/- 9.71 kJ/mol, E-x2 = 588.77 +/- 28.88 kJ/mol and E-x3 = 330.26 +/- 3.61 kJ/mol on kissinger plotting in this study.
