The microstructure evolution mechanism in adiabatic shear band in commercial pure titanium (TA2) at high strain rate ( ≈105~106/s) were studied. The nanosized recrystallized grains (about 50 nm in diameter) within the center of adiabatic shear band (ASB) were observed by means of transmission electronic microscope (TEM). A Rotational Dynamic Recrystallization (RDR) mechanism can explain the microstructure evolution (ie. nanosized grains was formed within 5-10μs) in ASB. Kinetics calculations indicated that the recrystallized small grains were formed during the deformation and didn’t undergo significant growth by grain boundary migration after deformation.
Keywords:shear band , microstructure evolution , dynamic recrystallization
