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...

Stationary shoulder friction stir processing (SSFSP) in thick AZ31B magnesium alloy was performed to refine the microstructure followed by evaluating corrosion behavior. The use of stationary exhibited low heat input and small temperature gradient across thickness zone (SZ). Moreover, smooth surface morphology with little flash obtained. probe-dominated SZ developed fine equiaxed uniform grain ...
