Microstructure and properties of diffusion bonded Ti-6Al-4V parts using brazing-assisted hot isostatic pressing

► A low cost method of diffusion bonding has been developed for complex-shaped components of Ti6Al4V. ► Vacuum brazing has been used to seal the periphery to allow encapsulation-free HIPping. ► The tensile properties of the bonds are comparable with those of the bulk material, but the fatigue life was slightly reduced.
