Abstract Ti-6Al-4V (Ti6Al4V or Ti64) is the most commercially used heat treatable alloy in titanium alloys. However, room temperature (RT) formability of this alloy is very poor and it is almost impossible to produce complex shaped parts. It has significant post uniform elongation at high temperature deformations. In this study, a previously proposed softening model (SM) for aluminum-magnesium (Al-Mg) alloys was improved in order to increase flow curve prediction capability for Ti-6Al-4V alloy having a high softening tendency at elevated temperatures. The improved model was called as Improved Softening Model (ISM). Results indicate that the ISM has more accurate prediction than the SM for Ti-6Al-4V alloy.
