Abstract The microstructure of adiabatic shearing band for β-Ti alloy deformed at high strain rate was observed undermetallographic microscope and SEM. Three types of adiabatic shearing bands, namely, the deformation band, the transformation bands with fine stripped microcrystalline structure and with equiaxied very fine microcrystalline structure are found in sequence Under very large deformation, it may be cracked along the adiabatic shearing band With regard to discuss the criterion of adiabatic shearing, the distinction among the adiabatic shearing deformation, the adiabatic shearing fracture and the thermoplastic instability is important
