| Abstract: |
| Evolution process of shear bands of tungsten fiber reinforced Zr-based bulk metallic glass matrix composite in deformation process was investigated. It is found that no shear band forms in the elastic stage, the shear band forms and develops in the plastic deformation process. Moreover, the number of shear bands increases with the increase of the deformation quantum, and the shear band spacing decreases with the increase of the deformation quantum. When the shear band spacing reaches the critical value, shear cracks occur and continuously extend, finally resulting in the fracture failure. |
