    摘要: A method of manufacturing an article (10) from two metal workpieces (30,32), the first and second metal workpieces (30,32) define the outer profile of the article (10). The second workpiece (32) is thicker than the first workpiece (30). The first workpiece (30) has two flat surfaces (34,36) and the second workpiece has one flat surface (38) and one machined (42) surface (40). Stop of is applied to surface (34) to prevent diffusion bonding at preselected areas. The workpieces (30,32) are assembled into a stack (58) so that the flat surfaces (34,38) are in abutment. Heat and pressure are applied to diffusion bond the workpieces (30,32) together to form an integral structure (60). The integral structure (60) is placed in a die such that the first workpiece (30) faces a convex surface of the die. The integral structure (60) is heated to cause the integral structure (60) to be hot creep formed on the convex surface of the die. The integral structure (62) is hot formed in a superplastic forming die by heating and internally pressurising the integral structure (62) to cause a preselected area of the second workpiece to be hot formed to produce the article (10).

    摘要: A transversely twisted hollow airfoil member is provided by diffusion bonding together airfoil components each having a skin or shell (32) in the form of a partial airfoil twisted transversely along its length (L) and one or more internal support ribs (50, 52, 54) having bonding surfaces (50a, 52a, 54a) which are not twisted transversely along their length. Each support rib extends substantially normal to a bonding plane (T) defined by bonding surfaces on the supporting ribs. As a result of the rib and bonding surface orientation, the airfoil components can be forged and the components bonded together at elevated temperature in short times between dies movable by high pressure toward one another normal to the bonding surfaces.
