加入微量镉后Mg61Cu28Gd11块体非晶合金的室温纳米压痕蠕变行为
Room Temperature Nanoindentation Creep Behavior of Mg61Cu28Gd11 Bulk Amorphous Alloy After Adding Tiny Cadmium
摘 要
采用纳米压痕法研究了Mg61Cu28Gd11和加入微量镉后(Mg61Cu28Gd11)99.5Cd0.5块体非晶合金的室温压痕蠕变行为, 并通过获得的蠕变位移、蠕变速率敏感指数和蠕变柔量分析了合金的蠕变机制。结果表明: 两种非晶合金都具有较低的室温蠕变敏感指数, 其室温蠕变机制主要为局部剪切流变, 特别是加入微量镉后非晶合金具有更高的硬度和弹性模量、更低的蠕变速率敏感指数和更小的蠕变柔量, 具有更好的抗蠕变性能和更低的应力松弛状态。

Abstract
The nanoindentation creep behaviors of Mg61Cu28Gd11 and (Mg61Cu28Gd11)99.5Cd0.5 bulk amorphous alloys after adding tiny Cd at room temperature were studied by means of nanoindentation. Their creep mechanisms were analyzed by creep displacement, creep rate sensitivity index and creep compliance. The results show that the amorphous alloys had lower room temperature creep sensitivity index and their room temperature mechanisms were main local shear flow. The amorphous alloy after adding tiny Cd exhibited higher hardness and elastic modulus, lower creep rate sensitivity index and smaller creep compliance, better creep resistance and lower stress relaxation.
