N2 - This study demonstrated a possibility of ductility improvement in high strength β titanium alloys in the as-solution treated condition through the investigation of tensile properties and deformation microstructures in the Ti-lOMo and Ti-l5Mo base alloys with various β phase stability. The Ti-10Mo-2Fe and Ti-15Mo-5Zr alloys with an intennediate β phase stability showed a combination of high yield strength and large uniform elongation due to the heterogeneous deformation by dislocation slip and {332}<113> twinning. It was suggested that the deformation transition occurs partially between the slip and the twinning caused by the inhomogeneous elemental distribution.
