Résumé

A ternary beta-metastable titanium Ti-9Mo-6W (wt.%) was designed. A very high work hardening rate close to 2100 MPa and a uniform deformation larger than 35% were recorded, thanks to combined transformation-induced plasticity and twinning-induced plasticity effects. In this paper, detailed microstructural analysis was performed to understand the deformation process. Various mechanisms, {332} < 113 > mechanical twinning, stress-induced omega phase and stress-induced alpha '' martensite were identified after mechanical testing, resulting in a complex network of deformed microstructures with very special synergetic features.
