Abstract

The liquid Mg–Zn–Y alloy was conditioned by an application of high-intensive shearing with a pair of intermesh twin screws prior to high-pressure die casting (HPDC). Melt conditioning produces a uniform microstructure with fine grain size and high integrity. The microstructure was analyzed thoroughly, and the solidification characteristics of the melt-conditioned HPDC (MC-HPDC) structure were discussed. The enhancement in I-phase precipitation and the improvement in mechanical properties of MC-HPDC Mg–Zn–Y alloy can be achieved through cyclic annealing.
