Abstract
Mg-8Li-3Al-xY(x=0.5,1.0,3.0) alloys were prepared with vacuum induction melting method.Effect of yttrium content on microstructure of the alloys was studied.Results show that yttrium causes the α(Mg) phase refinement and spheroidization.With the increase of Y,the Al2Y phase exists in alloy.
