Microstructure and mechanical properties of moderate-speed extrudable Mg-Gd-Sm-Zr alloy

Materials Research Express, 2021
Extrusion Mg-Gd based alloy has the excellent mechanical properties, but usually at the sacrifice of productivity. In this paper, we designed a Mg-10Gd-1Sm-0.5Zr alloy, and have successfully extruded it with a die-exit speed of 3.2 m min ^−1 , and the ...
