摘要： Examples are provided for fabricating a finished workpiece (120) having a shaped portion. One example includes: a superplastic formation diffusion bonding (SPFDB) component; a cold spray additive manufacturing (CSAM) component; and a mold (150) having a concavity (152). Various configurations can operate on a workpiece with the SPFDB and CSAM components in different orders. An example is configured to cold spray (with the CSAM component) an additive material onto the workpiece (110); and perform superplastic forming (with the SPFDB component) on the workpiece (110) with the mold (150), thereby rendering the workpiece into the finished workpiece (120) having the shaped portion (122). The shaped portion conforms to a shape defined by the concavity. Cold spraying results in an increased thickness of the finished workpiece in a target region (124), which can provide structural reinforcement, and which can have a tapered edge. The workpiece can be a metal substrate made of titanium, aluminum, stainless steel, or another material.

摘要： A process for manufacturing a shaped sandwich panel includes arranging a sandwich panel (66) adjacent a die (74). The sandwich panel (66) includes a core layer (26') arranged between and connected to a first layer (22') and a second layer (24'). The core layer (26') includes a plurality of apertures (38) that extend through the core layer (26') to the first layer (22'). The first layer (22') engages the die (74). Fluid within the apertures is pressurized to a pressure adequate to at least partially form the sandwich panel (66) to a geometry of the die (74).

摘要： In a method of manufacturing an article (28) by diffusion bonding and superplastic forming stop off material (122) is applied to prevent diffusion bonding in a predetermined pattern on a first surface (106) of a first metal workpiece (100) and the predetermined pattern is spaced from the edges of the first surface (106) of the first metal workpiece (100). Stop off material (124) to prevent diffusion bonding is applied in a predetermined position on the first surface (106) of the first metal workpiece (100) and the predetermined position extends from the predetermined pattern of stop of material (122) on the first surface (106) of the first metal workpiece (100) towards one edge of the first surface (106) of the first metal workpiece (100). A recess (130, 132) is provided in a second predetermined position on the second surface (108) of the first metal workpiece (100) or a fourth surface (112) of a second metal workpiece (102), the recess (130,132) extends towards the same edge of the first metal workpiece (100) or a corresponding edge of the second metal workpiece (102). The first and second metal workpieces (100, 102) are diffusion bonded together. During superplastic forming the recess (130, 132) and the stop off material (124) in the predetermined position define an inflation passage (148) for superplastic forming of the metal workpieces (100, 102) to a hollow article (28).

摘要： Disclosed is apparatus (1) and a method for the stretch forming of an elongated hollow metal section (6), such as an aluminum extrusion. The apparatus and method uses one or more constraining means (15, 20, 21) secured to a forming die (9) and a die extension (22) to constrain and support the walls of the elongated hollow metal section (6) against the forces produced by air pressure within the interior of the hollow metal section (6). The apparatus and methods disclosed herein prevent the formation of wrinkles, crimps and bulges in the walls of the elongated hollow metal section (6) during the stretch forming and reshaping thereof.
