Abstract—The structure and the mechanical properties of magnesium alloys, which are close in composition to an IMV7-1 alloy (Mg–Y–Gd–Zr system), are investigated after rotary swaging (RS). The mechanical properties are measured after RS or after RS followed by aging at 200°C for up to 64 h. The alloys are aged directly after RS or RS followed by homogenization at 515°C. RS is found to harden the investigated alloys due to grain refinement and intense twinning. Aging after RS results in additional hardening of the alloys as a result of the decomposition of a supersaturated magnesium solid solution. Annealing after RS increases the grain size in the alloys due to normal grain growth and, thus, decreases the strength properties of the alloys.
