英文摘要: In order to improve the mechanical properties of Mg-Li alloy with single β phase structure, Mg-12Li-3Al- x Nd ( x =0.3, 0.7, 1.1, 2.0wt.%) alloy was prepared. Subsequently, the as-cast microstructure and mechanical properties were observed and tested. The results showed that the structure of Mg-12Li-3Al- x Nd ( x =0.3, 0.7, 1.1, 2.0wt.%) as-cast alloy was composed of β phase matrix and Al2Nd, Al11Nd3, MgLiAl2, Al4Li9 and AlLi phases. With the increase of Nd content in the alloy, the Al-Nd intermetallic compounds have a trend to change from needle-like Al11Nd3 to granular Al2Nd. The hardness of as-cast Mg-12Li-3Al- x Nd ( x =0.3, 0.7, 1.1, 2.0wt.%) alloy was stable at room temperature. The...
