| 330 | _aThe titanium alloy Ti-6Al-4V with strongly nonequilibrium [alpha]-and [beta]-phases has been studied for the first time. For this, it was subjected to cross-helical rolling (CHR) at T=1000°C (above the polymorphic transformation temperature), and then quenched in water in order to partially preserve vanadium in the [alpha]-phase, and aluminum in the [beta]-phase. Under active uniaxial tension, the non-equilibrium VT6 alloy was deformed in the absence of strain hardening at room temperature. Alloys treated with CHR below the polymorphic transformation temperature showed traditional parabolic hardening. The non-equilibrium of the VT6 alloy caused a strong increase in its impact toughness at low temperatures down to T=-70°C. The fatigue life of a nonequilibrium alloy has doubled. If the initial alloy has ductile-brittle fracture at low negative temperatures, then the nonequilibrium alloy deforms viscously with all signs of structural turbulence. Structural turbulence in a nonequilibrium alloy manifests itself in the temperature range from 20 to -70°C, during deformation of 3D-printed samples, under conditions of shock separation of diffusion-sintered multilayer VT6 alloy packets. | ||
