Pressure welding using the phenomenon of structural superplasticity is a relatively new technological method based on the additive principle of forming parts. The problem of the quality of a solid-phase joint, which is well studied for superplastic titanium alloys, requires a verification of the versatility of the approaches used to solve it for heat-resistant nickel alloys, as well as for welding of dissimilar crystalline materials. The possibility of reducing the temperature of pressure welding by using low-temperature superplasticity of ultrafine-grained (UFG) crystalline alloys is considered.
