Al-Mg合金是一种低成本、低密度的铝合金,在变形过程中表现出显著的强化作用。本文以工业纯Al、Al-0.5Mg和Al-4.1Mg合金为研究对象,研究了Mg对材料的强化作用。在铸态合金中发现少量的Mg固溶强化。而高压扭转对合金的强化效果更为显著。Al-4.1Mg合金由于变形诱导的超细晶、高密度层错和Mg偏析,获得了~800 MPa的超高强度。
Al-Mg alloys are a series of low cost and low density Al alloys, which show remarkable strengthening during deformation. In this work, study of commercial purity Al, Al-0.5Mg and Al-4.1Mg alloys was carried out to investigate the effect of Mg on materials strengthening. Slight solid solution strengthening by Mg addition is found in the as-cast alloys. While further significant strengthening effect is achieved in the alloys produced by high pressure torsion. An extraordinarily high strength of ~800 MPa is achieved in the Al-4.1Mg alloy, as a result of deformation induced ultrafine grains, high density stacking faults and Mg segregation.
