摘要：
The effect of hot rotary swaging and subsequent annealing on the microstructure and mechanical properties of magnesium alloy WE43 of the Mg – Y – Nd – Zr system is studied. The optimum temperature of rotary swaging providing refinement of the microstructure, change in the preferential grain orientation, strain hardening and growth in the strength is determined. It is shown that subsequent annealing at 400°C for 60 min raises the ductility, causes the appearance of equiaxed grains, and removes the strain hardening, which makes it possible to perform further deformation.
