The adiabatic shear characteristics of a typical near α-type Ti-6Al-2Zr-1Mo-1V Ti alloy at different strain rates have been investigated by hat shaped specimen. The results show that the dynamic stress-strain curve can be divided into three typical stages, which correspond to strain hardening, heat softening and shear localization, respectively, and finally develops into mature ASB；Close to the shear band，the primary α and second α distorted or even fractured in the transition zone，and showing the characteristics of twin deformation；In the near shear zone, the Kernel average misorientation(KAM) increases, α phase which is favorable to dislocation slip/twin orientation has a preferential plastic deformation, forming substructure, grain fragmentation and dynamic recrystallization. With the increase of strain rate, the width of shear band extended, and the vortex structure is supplemented by the coordination and adaptive deformation. The elastic modulus and microhardness of α-phase and β-phase of ASB ,near ASB and matrix were analyzed by nano indentation test, the results show that the adiabatic shear band of the this alloy is a softening band, and the width of the heat-affected zone is about 30μm around ASB.
