Alloy Development of High Toughness Mg-Gd-Y-Zn-Zr Alloys
MATERIALS TRANSACTIONS, 2006 The effects of zinc addition on microstructure evolution and mechanical properties of Mg-Gd-Y-(-Zr) based alloys are investigated in details using OM, TEM, Vickers hardness tests and tensile tests. Specific line-shaped structure is formed inside of matrix grain in the as-cast specimen.

Mechanical properties of Mg-8Gd-3Y-0.5Zr alloy with bimodal grain size distributions
Journal of Magnesium and Alloys, 2017 The Mg-Gd-Y-Zn-Zr alloys are representational and potential age-hardening systems as reported in the past ten years, but their mechanical properties are still dependent on the grain size and its distribution. The effect of bimodal structure on mechanical
