Paper Title:
Microstructures and Properties of Zn-Al-Si Cast Alloys
  Abstract

Zn-Al-Si cast alloys with different content Al and Si such as ZA11Si1, ZA24Si3 and ZA40Si5 were fabricated by metal mould. Zn-Al-Si alloys were composed of α+η or α+η and Si phase. The dendritic particles in ZA11Si1 were smaller than ZA24Si3 and ZA40Si5 and Si phase did not appear in it. The microstructures of ZA24Si3 and ZA40Si5 alloy were larger dendrites and more lump, strip Si phases were dispersed unevenly. ZA24Si3 had the highest mircoharness compare with ZA11Si1 and ZA40Si5, which had the almost same microhardness. ZA11Si11 wear volume was the lowest than those of the pure Zn and the other two Zn-Al-Si alloys and its wear resistance was the best. 11 wt% Al and 1 wt% Si content in the Zn-Al-Si alloy favored the microhardness and wear resistance improvement.
