Effects of temperature and initial microstructure on the equal channel angular pressing of Ti-6Al-4V alloy

Equal channel angular pressing of Ti-6Al-4V alloy was successfully carried out isothermally above 600 C. The equiaxed microstructure presented more uniform material flow than the Widmanstatten microstructure, which was discussed in relation to flow softening behavior of the two microstructures.
