摘      要：In this study,a rolled AZ31 bar with square section was *** reciprocating torsion was performed to maintain the shape of the *** microstructure evolution of AZ31 bar during torsion and its influence on compressive anisotropy were investigated in *** showed that reciprocating torsion can simultaneously enhance yield strength in three compressive directions,and reduce compressive *** torsion generated profuse dislocations and{10–12}twin boundaries to harden the micro-hardness and yield *** torsion can also generate new texture component which is mainly from the orientation of newly generated{10–12}*** new twin-structures will be responsible for the reduction in compressive ***,uneven deformation features in twisted sample were systematically investigated.
