Preliminary studies show the existence of Plasticity induced Transformation in metastable β-Titanium alloys (PiTTi), an effect similar to TRIP in steels. Extensive studies have been carried out to understand the defining heat treatment parameters to promote PiTTi effect in Ti-10V-2Fe-3Al (wt.%) alloy for β and/or α+β conditions. Compression testing results show stress-induced martensite formation in β and β+(α+β) microstructures with ∼20% increase in strength. Based on Ghosh and Olson theory for martensite nucleation, a model was developed to estimate the M s temperature, a critical parameter for PiTTi optimization. The chemical inhomogeneities in the β phase are employed to predict its PiTTi ability.
