| Research Abstract |
The effect of the precipitation of crystalline particles induced by the thermoplastic deformation of Zr-based bulk metallic glass on its elastic modulus at room temperature was investigated. In the results, the material shows the strength degradation and the brittleness, when the elastic modulus induced slightly. On the other hand, the significant decrease of the elastic modulus due to a certain thermoplastic deformation changes the Zr-based bulk metallic glass to more flexible material with lower elastic modulus than the as-cast.
