Effect of Deformation and Prestrain Mode on the Flow Behavior of Ti-6Al-4V

Abstract

The effect of strain path on the plastic-flow behavior of Ti-6Al-4V with a colony-alpha perform microstructure was determined. Specifically, the stress-strain response in compression following a prestrain via torsion, compression, or rolling was interpreted. It was found that the flow-softening parameter was dependent on the level of the prestrain, but independent of the mode of prestrain. After a prestrain of ~0.3, however, it decreased very slowly.
