摘要：
The deformation mechanisms of Ti-10Mo (wt.%) alloy subjected to different quasi-hydrostatic pressure values were investigated under constrained compression using stage of high-pressure torsion apparatus. Deformation products contain {332}< 113 > mechanical twinning, stress-induced alpha '' martensitic phase and stress-induced omega phase. A volume expansion accompanied stress-induced alpha '' martensitic phase transformation is 2.06%. By increasing the applied pressure from 2.5 GPa to 5 GPa, the dominant deformation mechanism underwent a transition from stress-induced alpha '' martensitic phase transformation to {332}< 113 > mechanical twinning.
