With the lightest green structural material for 21st century, a significant weight reduction effect was expected to solve lightweight problem in aerospace and other fields. However, material’s poor mechanical properties flammability limited its widely application such In this paper, GWK series alloys (Mg-5.3Gd-4.11Y-0.13Zr, Mg-5.5Gd-4.22Y-0.19Zr, Mg-5.46Gd-4.02Y-0.20Zr, wt.%) were designed, we ...
