Abstract

Mg-4Al-4Nd-0.5Zn-0.3Mn alloy was prepared by metal mould casting method. Microstructure, aging behavior, mechanical properties and fracture morphology of the alloy were investigated. The results showed that α-Mg, Al₁₁Nd₃, Al₂Nd and Mg₃₂(Al,Zn)₄₉ phases were the main phases of the as-cast alloy. And the long rod-like Al₁₁Nd₃ phase was decomposed to granular Al₂Nd through T6 heat treatment. The tensile strength was also enhanced by T6 treatment. The yield strength was increased by 17% and 21% at RT and 150 °C, respectively. It was mainly because that the precipitates were refined through T6 treatment and this became more benefit to hinder dislocations slipping.
