Dynamic recrystallization behaviors and the resultant mechanical properties of a Mg-Y-Nd-Zr alloy during hot compression after aging

Dynamic recrystallization (DRX) behaviors and the resultant mechanical properties were investigated using a Mg-Y-Nd-Zr alloy pretreated in solution and subsequent aging followed by hot deformation. In the aging sample containing statically precipitated particles, the occurrence of DRX takes place at medium strains and approaches a full development of final stable DRX grains, resulting in the formation of a weaker texture. The resultant tensile elongation of the alloy, hot deformed after aging treatment, reaches 18%, which is much higher than that of the one without aging treatment, i.e. 11%.
