Understanding the relationship between deformation behaviors and mechanisms is significant for the processing and application of metastable β titanium alloys. Here we aim to investigate and evaluate the abnormal yield strength and strain softening of a Ti-15.1Mo-2.77Nb-3.1Al-0.21Si alloy at room temperature. This alloy exhibits a high yield strength of 970 MPa, followed by the continuous stress drop behavior in the entire engineering strains (or true strains of 0.018 ∼ 0.056). Digital image correlation (DIC) reveals that the flow stress drop ...
