Effects of Grain Refining Elements on the Mechanical Properties and Mold Filling Ability of AZ91D Alloy

Jeong‐Min Kim, Joonsik Park

Open full text 2 citations

Abstract

Various grain refining alloying elements such as Sr, TiB, and Ca were added to AZ91D and their effects on the mechanical properties and mold filling ability were investigated. The average grain sizes of those alloys were significantly reduced by the small amounts of the alloying elements. Ca addition was the most remarkably effective in reducing the grain size, however it was found to deteriorate the mold filling ability and tensile properties. TiB addition was observed to be the most efficient for both grain refinement and mold filling.
