Abstract
Adiabatic shear susceptivity of four typical structure for Ti-6Al-4V alloy was evaluated by critical strain which stress collapse takes place, and the critical fracture velocity was tested by Taylor bar technology. Also the relationship between adiabatic shear susceptivity and critical fracture velocity was explored. The results show that there are an adiabatic shear susceptivity differences among four kinds of microstructure in Ti-6Al-4V, in which the bimodal microstructure is of lowest adiabatic shear susceptivity; under the condition of Taylor bar impact at top speed, the adiabatic shear deformation will result in the rupture of four kinds of structure in Ti-6Al-4V, and the critical fracture velocity is in proportion to critical strain.
