“…Obviously, the application of these treatments to β titanium alloys will have its own characteristics compared to conventional (α + β) alloys. In particular, it is possible to change the development of the processes of formation and evolution of the microstructure, phase transformations, occurring in UFG titanium alloys directly during severe plastic deformation [24,25] or subsequent heat treatments [21,23]. In connection with the above, in the present work, comparative studies of the effect of annealing (aging) at a temperature of 723 K on the structural-phase state and mechanical properties of the β titanium alloy VT35 (Ti-15V-3Cr-3Al-3Sn-1Mo-1Zr) were carried out after quenching from the β-phase region (1073 K) and various deformation-thermal treatments using the methods of severe plastic deformation.…”
