| 摘 要： | In this paper, a rapidly solidified Al-Si-Fe-Cu-Mg alloy was prepared by spray deposition. The microstructure of the alloy includes silicon phase and δ-(Al,Fe,Si). Al8Si6Mg3Fe, FeAl2 and small FeSi2 phases. The reasons of the formation of silicon and δ-(Al,Fe,Si) phase were analyzed. The tensile properties at the temperatures of room to 350℃ were investigated, and the strengthening mechanism was suggested. The wear resistance and cutability of the alloy were measured as well.
