摘要:

通过电弧熔炼并利用吸铸的方法制备了长70 mm、直径3 mm的Zr63Al10Ni10Cu14Nb3大块非晶合金.热稳定性分析表明:该合金具有较大的过冷液相区.室温压缩实验显示合金具有很高的屈服强度,在合金发生屈服之后应力-应变曲线上有明显的锯齿现象和一个明显的应变软化阶段.结合断口形貌特征,分析并讨论了非晶合金的剪切断裂机理.

Abstract:

Zr70Al3Ni63Cu10Nb10 bulk amorphous alloy with a length of 14 mm and a diameter of 3 mm was prepared by arc melting and suction casting. The thermal stability analysis shows that the alloy has a large subcooled liquid phase region. The room temperature compression experiment showed that the alloy had high yield strength, and there was obvious aliasing phenomenon and an obvious strain softening stage on the stress-strain curve after the alloy yielded. Combined with the morphological characteristics of fracture, the shear fracture mechanism of amorphous alloy was analyzed and discussed.
