N2 - It is shown that pre-straining with deformation twinning is a novel approach to enhancing the uniform elongation of a high-strength β-type Ti-15Mo alloy (mass%) with isothermal ω-phase precipitation. Pre-existent mechanical {332}〈113〉 twins hinder the early onset of plastic instability (necking) after yielding, which is often caused by the presence of the isothermal ω-phase, and enhance the uniform elongation markedly from 0% to 13% at a yield strength level of 900MPa.
