摘要	This study investigated the effect of Sc addition on the microstructure and mechanical properties of a high-Zn-concentration Al (Al-49Zn) alloy. The addition of 0.5Sc obviously refined the Al grains and Zn phases in the Al-49Zn alloy during solidification. It also suppressed the Al grain coarsening and Zn dissolution in the Al-49Zn alloy during heat treatment because of the pinning effect of nanoscale Al3Sc precipitates and Sc atoms. Given its refined structure and high thermal stability, the Al-49Zn-0.5Sc alloy showed high hardness and mechanical stability after heating.; This study investigated the effect of Sc addition on the microstructure and mechanical properties of a high-Zn-concentration Al (Al-49Zn) alloy.
