摘要

Dynamic mechanical properties of AZ31B sheet were carried out incompression along rolling direction using split Hopkinson bar (SHPB) at the strain rate of 1200s^-1. Post-mortem observations were conducted using optical microscope and transmission electron microscope. The results show that both {101̄1}/<101̄2> and {11̄02}/<101̄1> twinning are the plastic deformation mechanisms at the strain of 0. 003, which is different from the {101̄2}/<101̄1> twinning deformation mechanism under quasi-static loading condition. The evolution of microstructure inside twinning consists of parallel basal stacking faults, parallel dislocation arrays of different orientations to twin boundary and dislocation cells.
