摘　　要：对Al-Zn-Mg-Cu合金进行3 GPa压力热处理,利用纳米压痕法研究了该处理对Al-Zn-Mg-Cu合金纳米压痕蠕变性能的影响。结果表明:3 GPa压力处理前后Al-Zn-Mg-Cu合金在室温下能发生压痕蠕变,在不同压力和时间条件下,3 GPa压力处理能减小Al-Zn-Mg-Cu合金的室温蠕变量,提高合金抗蠕变能力。Al-Zn-Mg-Cu alloy was treated at 3 GPa pressure, and the effect of high pressure treatment on the nanoindentation creep property of the alloy was investigated by using nanoindentation. The results show that indentation creep in Al-Zn-Mg-Cu alloy before and after 3 GPa pressure treatment can occur at room temperature. 3 GPa pressure treatment can reduce the creep deformation of Al-Zn-Mg-Cu alloy at room temperature under different pressure and time, which can lead to the increase of creep resistance of the alloy.
