Two titanium alloy turbine components are diffusion bonded together by preparing mating surfaces of the components to a high degree of smoothness, putting the surfaces in mating abutment, placing the components within a yoke in a vacuum furnace, evacuating the furnace, increasing the temperature of the furnace to about 960 DEG C., applying pressure across the interface between the components by means of a pressure bag between the yoke and the components, maintaining the vacuum, temperature and pressure for about 30 minutes, back filling the furnace with argon, increasing the pressure of argon to about 1000 atmospheres, maintaining that pressure and temperature for about two hours, and then reducing the pressure to atmospheric and removing the diffusion bonded components from the furnace.
