Abstract

The targets of Ti-6Al-4V alloy were impacted by a 7.62 mm diameter armored steel ball with a speed of 0.662 km/s. The damage behavior of crater as well as microstructure evolution was observed. Results show that the formation of adiabatic shear band of material goes through three processes of initiation, expansion and full evolvement. The stress, local shear strain, hardness, heat softening and the shape of the ball at the initialization have influences on the damage behavior of crater and the microstructure evolution of Ti-6Al-4V alloy at the moment of penetration armored plate. The microstructure and damage behavior of crater are quite different, during which the stress plays a very important role.
