Grain size and microhardness evolution during annealing of a magnesium alloy processed by high-pressure torsion
High-pressure torsion (HPT) was used to impose severe plastic deformation on a magnesium alloy AZ31. The material was processed for 0.5, 1, 2, 3, 5 and 7 turns at room temperature under a pressure of 6.0 GPa. Samples were annealed for 1800 s at temperatures of 373 K, 423 K, 473 K, 573 K and 673 K.
