Abstract

The shock induced mechanical response of two gamma-titaniurn aluminides has been investigated using the technique of plate impact. It has been found that the HEL, spall strength and shear strengths are all dependent upon the initial microstructure , with the material possessed of the duplex microstructure being the stronger. This is in agreement with quasi-static measurements. Shear strength has been observed to increase rapidly with increasing longitudinal stress, more so than in Ti-6Al-4V, indicating that the high degree of work hardening is an important factor in determining the shear strength of metallic and intermetallic materials.
