Abstract. In the evolution of characteristics in Mg alloys, combined influence grain refinement by severe plastic deformation (SPD) and alloying elements usually plays a crucial role. Rare earth (Y, Gd, Nd) combination with Zn have substantial impact on various compositions. this study, new dilute extruded Mg-Zn-Gd-Y-Nd alloy was exposed to 5 passes equal channel angular pressing (ECAP), die 90...
