Ductility Improvement in High Strength Ti-Mo Alloys by Transition of Deformation Mode

摘要：

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-10Mo and Ti-15Mo base alloys with various β phase stability. The Ti-10Mo-2Fe and Ti-15Mo-5Zr alloys with an intermediate 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.
