摘要/Abstract

摘要： 采用自然时效、人工时效和轧制后人工时效等工艺制备出具有不同显微组织的Al-7Mg-xZn-0.25Sc(x=0,1,2,3)合金。Zn添加导致Al-7Mg-xZn-0.25Sc合金在人工时效后形成Mg₃₂(Al, Zn)₄₉相。此外,Zn还促进Al-7Mg-xZn-0.25Sc合金在固溶处理过程中发生再结晶。轧制所引起的晶粒细化在降低Al-7Mg-xZn-0.25Sc合金界面滑动温度的同时,提高其高温阻尼值。Zn添加可有效地抑制Al-7Mg-xZn-0.25Sc合金在高温振动过程中发生晶粒粗化,进而提高该合金的阻尼稳定性。在所研究合金中,Al-7Mg-2Zn-0.25Sc合金表现出最优的阻尼性能。

Abstract: Al-7Mg-xZn-0.25Sc alloys (x=0, 1, 2, 3) with different microstructures were prepared via natural aging, artificial aging, and post-rolling artificial aging processes. The addition of Zn leads to the formation of Mg₃₂(Al, Zn)₄₉ phases in the Al-7Mg-xZn-0.25Sc alloys after artificial aging. Furthermore, Zn promotes the recrystallization of the Al-7Mg-xZn-0.25Sc alloys during the solution treatment. The grain refinement caused by rolling reduces the interfacial sliding temperature of the Al-7Mg-xZn-0.25Sc alloys while increases their high-temperature damping capacity. The addition of Zn can effectively inhibit grain coarsening of the Al-7Mg-xZn-0.25Sc alloys during high-temperature vibration, thereby improving the damping stability of the alloys. Among the studied alloys, the Al-7Mg-2Zn-0.25Sc alloy exhibits the optimal damping capacity.
