The effect of severe plastic deformation by multi-axial pressing followed by thermal treatment on the structure and mechanical properties of titanium alloy PT-3V (4.66% Al : 1.92% V) has been investigated. Submicrocrystalline structure formation is shown to dramatically improve the mechanical properties of the alloy at room temperature and to decrease the superplastic flow temperature interval by 250–300 K. Low-temperature annealing of the material in a submicrocrystalline state is found to cause further increase in the yield strength and ultimate strength as compared to the preannealing level, with the strain at fracture being nearly doubled.
