摘要: Abstract The binary Mg–Er alloys with respective concentration of 2.0 wt%Er, 4.0 wt%Er and 6.0 wt%Er were prepared via extruding annealing, their quasi-static mechanical properties investigated. It was found that after complete recrystallization, the “Rear Earth-texture” (RE-texture) develops Er incremental addition. Under both tensile compressive loadings, Mg–4.0 wt%Er Mg–6.0 wt%Er had flow stresses lower than Mg–2.0 wt%Er alloy. However, ductility higher elongation reduction alloy reached to 29.4% 42.3%, respectively, much usual pure magnesium. dependence on addition could be interpreted by RE-texture development c / a axial ratio allowing for activation additional plastic deformation modes.
