for 24 h and followed by aging treatment at 200 ?C for 12 h, the heat-treated alloy exhibits relatively high tensile and creep properties than those of the as-cast alloy. Key words: magnesium alloy..., and then the extending trend of microcracks would decrease. Accordingly, after solution heat treatment and aging, the mechanical properties of the AZ61-0.7Si alloy are improved, especially the elongation......

compositions of 7A05 Al alloy[3] are also listed in Table 1. 2.2 Procedure Four types of heat treatment processes, dual aging, deformation (25%) plus dual aging, pre-aging plus deformation (25%) plus dual aging, and retrogression and reaging(RRA), were carried out in this work and they are detailed in Table 2. After heat treatment, the tension and impact specimens were prepared from both......
