摘　　要：利用多向锻造强化变形铝合金,使铝合金的强度大幅度提高。结果表明,试样组织显著细化,且第二相微粒弥散分布,抗拉强度和硬度大幅度增加,强度和硬度大幅度提高,是由于组织显著细化。In this work, a wrought aluminum alloy be processed by multidirectional forging. The results show that the microstructure of alloy was refined markedly and the ultrafine cementite particles were dispersive distributed. The alloy exhibited high strength and high hardness. The strength and hardness is increased markedly due to refinement microstructure.

关 键 词：铝合金 多向锻造 强度 硬度
