Abstract
Dynamic failure behaviors of high reinforcement content TiB2/Al composites were experimentally investigated using split Hopkinson pressure bar (SHPB). The TiB2/Al composites showed high flow stresses and good plastic deformation ability at high strain rates. Adiabatic temperature rise decreased the flow stresses of TiB2/Al composites, which was verified by the prediction of Johnson–Cook model. While the predictions by Cowper–Symonds model exhibited obvious strain hardening characteristic, the values of which were much higher than those of the Johnson–Cook model and the experimental. The composites were failed macroscopically in brittle fracture and some phase transformation bands were found on the shearing surfaces. The dynamic failure behavior of TiB2/Al composites was predominated by the formation of adiabatic shear bands.
