摘　　要：研究了Zr、Cr和La的复合添加对铝的强化作用。结果表明,在铝中复合添加Zr、Cr和La可明显抑制铝的再结晶,并使铝强化。与同时加入Cr和La相比,同时添加Zr、Cr和La能更有效地抑制铝的再结晶,强化合金能力也略有提高。The strengthening effect of combined addition of Zr, Cr and La in aluminum has investigated. The results show that combined addition of Zr, Cr and La can inhibit recrystallization and strengthen alloys significantly. Comparing wih combined addition of Cr and La, combined addition of Zr, Cr and La has more obvious capability of inhibiting recrystallization, and its effect of strengthening effect also improve slightly.
