The mechanical response and microstructure evolution in a rolled AZ31B magnesium alloy were experimentally characterized using companion thin-walled tubular specimens under free-end monotonic torsion. made with their axes along the normal direction of plate. shear stress-shear strain shows subtle sigmodal shape that is composed four distinctive stages hardening. Basal slips tension twinning are...

The nucleation, grain growth of 34 coarse grains during annealing were tracked using a quasi-in-situ EBSD method. These had different orientations and most non-basal orientated. No preferable or special types boundaries identified. Only 9 nucleated from deformed due to initial large size limited boundary volume fraction. main nucleation site was dislocation cells subgrains in interiors. Their r...

The deformation and crack initiation mechanisms were analyzed in a textured AZ31B-O Mg alloy subjected to fully-reversed, strain-controlled cyclic along the rolling direction after 50 cycles (approximately 33% of fatigue life). Distinct bands corresponding pyramidal slip or tensile twins found 538 grains out 2100 grains. Slip trace analysis showed that 72.3% 18.4% twin boundaries. Both twinning...
