英文摘要	Phase evolution and morphology of Fe₃O₄-Si-Al powder mixtures during ball milling from 30min to 20h were investigated. A 3-h critical milling was necessary for the occurrence of mechanically activated combustion reaction. The reaction results in the formation of Fe (Si), Fe₃Si, and α-Al₂O₃. During ball milling from 3 to 20h, Fe (Si) and Fe₃Si were combined into disordered Fe₃Si intermetallic and Fe₃Si-Al₂O₃ composite powder was formed. The presence of in situ formed alumina leads to a decrease in crystallite and particle sizes. The Fe₃Si-Al₂O₃ particles after milling for 20h had a crystalline size of 10～12nm.
