ABSTRACT:
A method for shear forge bonding two or more metal parts having forging compatible compositions is comprised of the steps of sizing parts to be joined across a forged bond line, disposing those parts in forging dies configured to present them in a bonding-effective orientation, shearing surfaces, one on each of the metal parts, located proximately and opposite one another across a gap, under controlled conditions of temperature and atmosphere selected to prevent the formation of any bonding disruptive surface contamination on the sheared surfaces, and then finally forging those parts to close the gap and bring the sheared surfaces into contact under controlled conditions of temperature, pressure, atmosphere, and outer diameter constraint to yield a shear forged bond between the sheared surfaces.
