strain rate, dislocation glide and twinning are present at the same time. At the strain rate of 2 964 s-1, adiabatic shear band can be found easily, even at the strain rate of 1 537 s-1 adiabatic shear localization zone can be found. In adiabatic shear localization zone, there are fine recrystallization grains. But in adiabatic shear band, the grains cannot be identified by optical......
