Effect of Intensive Melt Shearing and Zr Content on Grain Refinement of Mg-0.5Ca-xZr Alloys

Abstract:

The effect of intensive melt shearing and Zr concentration on grain refinement of Mg‑0.5Ca-xZr alloy has been investigated experimentally. It was found that without intensive melt shearing, the grain size of Mg-0.5Ca alloy decreased from 290 µm to 76 µm when the Zr concentration is varied between 0 and 1 wt.%. However, intensive melt shearing makes the grain size of the same alloys first decrease and then increase with increasing Zr addition. The minimum grain size (85 µm) was achieved at 0.4 wt.% Zr.
