Abstract
A method of diffusion bonding three metal work pieces to form a fan blade, where each workpiece has a flat surface and an excess portion larger than a predetermined size needed to produce a finished fan blade; longitudinally extending slots are provided to interconnect the flat surfaces of the excess portions of the work pieces; the work pieces are assembled into a stack with the flat surfaces in mating abutment and the stack is evacuated from one end of the stack through the slots; heat and pressure are applied across the thickness of the work pieces to diffusion bond the work pieces together to form an integral structure; the excess portions with the slots are then removed.
