| 摘 要： | 研究体积分数为60%的连续钨丝/Zr41.2Ti13.8Cu12.5Ni10Be22.5块体金属玻璃复合材料准静态压缩变形过程中剪切带的演化过程。发现在弹性变形段不形成剪切带,剪切带是在塑性变形过程中产生并发展的,且剪切带的数量随着变形量的增加而增大,间距随着变形量的增加而减小;当间距减小到一定值时产生剪切裂纹并不断扩展,最终导致断裂破坏。

| 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. |
