Abstract

Dynamic mechanical properties and fracture morphology related to adiabatic shear band formed in pure titanium TA2 have been observed by means of specially designed specimen in a Hopkinson pressure machine at high strain rate of 10³ s^-1. Microstructure and fracture morphology of the specimens are observed by scanning electric microscope (SEM) and transmission electric microscopy (TEM). The observation indicates that the material undergoes uniform deformation at a low strain rate to symmetry uniform deformation in range of middling strain to asymmetry deformation at high strain before it is damaged. The materials are characterized by thermo-plastic instability. The fracture morphology is characterized by tenacity pit and tenacity veins.
