| 摘 要： | 大块非晶合金具有高强度(～2 GPa),大的弹性极限(2%～3%)及良好的耐腐蚀性等优异性能,但室温塑性低限制了大块非晶合金在工程上的实际应用.本文从大块非晶合金变形与断裂的微观机制出发探讨了其室温脆性的本质,并总结了通过在大块非晶合金基体中引入第二相(外加或原位生成)来改善其室温塑性的复合韧化研究进展.

| Abstract: | Bulk metallic glasses have unique mechanical properties, including high strengths (~2 GPa), large elastic limits (2%~3%), and excellent resistance to corrosion, but the poor room temperature ductility restricts its applications as structural materials. In this paper, the room temperature brittleness of bulk metallic glasses was discussed based on the deformation and fracture mechanism, and the progress in improving room temperature ductility by introducing second phase in the amorphous matrix was summarized. |

| Keywords: | bulk metallic glasses room temperature ductility shear band toughen |
