Pressure welding nanostructured titanium sheets of Ti-6Al-4V alloy under conditions of low temperature superplasticity
The solid-phase weldability of titanium microcrystalline structures allow Ti-6Al-4V in the temperature range 650…750 <sup>о</sup>С is studied. The deformation origin of solid state joining of the nanostructured alloy during pressure welding in the conditions of low temperature superplasity. As the pressure welding temperature is decreased from 750°C to 650°C the shear strength of both the base material and the SSB material is noticeably increased.
