Abstract

A novel metastable β-type Ti–6Mo-3.5Cr–1Zr alloy is designed using d-electrons theory to introduce diverse phase transformations. Stress-induced ω (SIω) phase transformation dominates the initial deformation, while the SIω bands are transformed to α+β phase as the strain increases. The sequential mechanism associated with β→SIω→α+β is first reported in titanium alloys.
