Effects of microstructure on the adiabatic shearing behaviors of titanium alloy

▶ The microstructures have a significant effect on adiabatic shear sensitivity of Ti-1300 alloy. ▶ The critical strain for the initiation of shear bands in α + β lamellar is less than that in β phase. ▶ The α + β lamellar experiences more extensive microscopic damage than β phase. ▶ The α + β lamellar is more susceptive to adiabatic shearing than β phase at the same strain rate.
