Enhancing strength and creep resistance of Mg–Gd–Y–Zn–Zr alloy by substituting Mn for Zr

Journal of Magnesium and Alloys, 2019
The age-hardening behavior and mechanical properties of the extruded Mg-2Gd-1.2Y-0.5 Zn (at.%) alloy with Zr or Mn additions were investigated. The results show that Mn added alloy exhibits more remarkable age-hardening response than Zr added alloy ...

Hot deformation behavior and microstructure evolutions of as-forged Mg-Gd-Y-Zn-Zr alloy

Journal of Materials Research and Technology, 2022
The hot deformation behavior of Mg-9.16Gd-3.03Y-1.44Zn-0.61Zr alloy was examined by hot compression experiments at 623–753 K with strain rates 0.1–20 s−1. Flow stress-strain curves developed an Arrhenius-type equation with adjustment for strain.
