“…The same approach was applied, for example, in the development of new titanium high-strength weldable alloys and welding wire. Due to the content of various β-stabilizing elements, it ensured their mutual substitution in the weld metal, which in turn provided their sufficient uniform total distribution [7,8,[27][28][29]. Similar cooperative effect of alloying elements was observed in the multi-component titanium alloys during phase transformations (upon interphase movement [30]), and during homogenization of high-temperature β-phase [31] under non-equilibrium conditions upon continuous high-rate heating.…”

Recently developed thermally hardenable medium-level alloyed titanium alloy T110 was studied from the viewpoint of microstructure influence on the mechanical behavior under quasi-static and high-strain rate deformation. The globular microstructures of two types differing in aspect ratio of α-globules were formed under thermomechanical processing conditions with different reductions (ε total = 2, and 3) and final annealing at 850 °C, 3 h. The thermally hardened state was formed by conventional solid-solution treatment at a temperature of two-phase α+β field (880 °C, 45 min), water quenching, and final aging (550 °C, 5 h). Stress-strain dependencies were estimated on tension with strain rates varied from 8•10 −4 to 4•10 −2 s −1 , as well as compression with a strain rate of 10 −3 s −1 (quasi-static) and under high-strain rates varied from 870 s −1 to 3520 s −1 ; the deformation with high-strain rates has been achieved using split Hopkinson pressure bar (SHPB) technique. The tested material was also assessed using strain energy (SE) parameter. A parallel study of the microstructure and crystallographic texture formed during testing allowed to propose a reliable deformation and fracture mechanisms, depending on the stress state (tension, compression) and strain rate. A special role of the initial microstructure is noted, which determines the plasticity of the tested alloy, the sites of pore nucleation, features of crack growth, as well as the localization of deformation, which is determined by the mode and rate of loading. It is established and explained why the best balance of strength and ductility, and thus, the highest SE values in the all tests carried out were ensured by the alloy in the state with a more uniform microstructure of globular morphology (after the rolling with reduction ε total =3), which, in turn, provided general superiority over the widely used Ti-6Al-4V alloy.

“…Attention should be paid to the fact that most of the stages of complex TMT modes occur under conditions far from thermodynamic equilibrium. Therefore, as early as at the stages of manufacturing, semi-finished titanium alloys and dynamic non-equilibrium processes (DNPs) are realized in melts, which aid in the formation of unique mechanical properties of titanium alloys of the class under consideration [9,10].…”

A simple technological method is proposed and tested experimentally, which allows for the improvement of mechanical properties in sheet two-phase high-strength titanium alloys VT23 and VT23M on the finished product (rolled metal), due to impact-oscillatory loading. Under impact-oscillatory loading and dynamic non-equilibrium processes (DNP) are realized in titanium alloys, leading to the self-organization of the structure. As a result, the mechanical properties of titanium alloys vary significantly with subsequent loading after the realization of DNP. In this study, the test modes are found, which can be used in the production conditions.
