Research on Grain Refinement of Sc and Zr Addition in an Al-Mg-Zn Alloy from Experiments and First-Principles Calculations

The effect of trace Sc and Zr on grain refinement of Al-5.0Mg-3.0Zn as-cast alloy was investigated by optical microscopy and scanning electron microscopy with EDS. The results indicated that the critical quantities of Sc and Zr for Al-Mg-Zn alloy to produce a significant refining effect were determi...
