摘　　要：采用惰性气体雾化法制备了Al-7.8Fe-1.3V-2.0Si合金粉末,通过高能球磨和粉末冶金工艺制备了Al-Fe-V-Si合金棒材,研究了材料的微观组织和在25,250,315℃下合金的压缩强度,结果表明,高能球磨可以使合金中Al12(Fe,V)3Si析出相分布更加弥散均匀,能使合金在25,250和315℃下的压缩强度得到大幅度提高。Al-7.8Fe-1.3V-2.0Si powders were produced by inert gas atomization, and extruded Al-Fe-V- Si bars were prepared with the powders obtained by ball milling and utilizing powder metallurgy route. Microstrueture examination and compression tests were performed at temperatures of 25, 250, 315 ℃. The results showed that the main precipitate phase in this alloy, Al12（Fe,V）3Si particle, became more uniformly distribution after ball milling, while compressive strength values of the alloy were increased much more at temperatures of 25, 250, 315 ℃.
