The microstructure of the alloy includes silicon phase and delta -(Al,Fe,Si), Al//8Si//6Mg//3Fe, FeAl//2 and small FeSi//2 phases. The reasons of the formation of silicon and delta -(Al,Fe,Si) phase were analyzed. The tensile properties at the room temperature to 350 degree C were investigated, and the strengthening mechanism was suggested. The wear resistance and cutability of the alloy were measured as well.
