Investigations of technological properties of new titanium alloy sheet VST2k have been conducted. It is found that the titanium alloy has a good solid state weldability and formability under conditions of superplasticity at temperatures 750-900C. By the method of SPF/DB sheet of VST2k alloy in a low-temperature superplasticity at a temperature of...

... Ti-6Al-4V is a most broadly used titanium alloy [1][2][3][4]. This is due to the wide spectrum of its mechanical properties, which are achieved by various thermo-mechanical treatments [1][2][3][4][5][6][7][8][9]. The resulting microstructures of the alloy are characterized by a stored deformation energy, which is related with dislocations, interfaces and other defects. ...
... The chemical composition of these materials complies with Russian standards (GOST 19807-91). The titanium sheet alloy has improved superplastic properties [19]. The three-layer material was obtained by diffusion bonding of the two plates with the intermediate sheet at temperature 800°C in a vacuum furnace under argon pressure using a flexible membrane. ...
