Mg alloys reinforced with long period stacking ordered (LPSO) phase are a new type of structural materials due to their excellent mechanical properties. However, the coarse LPSO phase in the castings usually aggregates at grain boundaries. In this work, ultrasonic vibration (UV) and rheosqueeze casting were applied on the Mg99.9-3x-Znx-Y2x-Zr0.1 (x=0.5, 1, 2) alloys to refine the LPSO structure. The semisolid slurries of Mg-Zn-Y-Zr alloys were prepared by UV and processed by rheosqueeze casting… CONTINUE READING
