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 оС 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.
