The microstructure evolution of near p-Ti alloys with initially lamellar and equiaxed microstructures subjected to dynamic loading was investigated. Results showed that during high strain rate compression, shear failure is more likely to occur in equiaxed micro-structure. Owing to temperature rise and stress concentration, the lamellar a phase in adiabatic shear band (ASB) zone was recrystallized and re-melted, while the equiaxed a phase transformed in strip-shaped following the propagating direction of adiabatic shear band. During high strain rate loading, the twinning transfer was observed b...
