Abstract
A first method of forming an object (400) includes wrapping foil around a preform (305) to provide a multi-layered structure including a plurality of layers of wrapped foil, and diffusion bonding the plurality of layers and the preform (305) together to form the object (400). A second method of forming an object includes wrapping foil around a preform (305) to provide a multi-layered structure comprising a plurality of layers of wrapped foil, removing the preform (305) from the multi-layered structure, and diffusion bonding the plurality of layers together to form the object (400). A third method of forming an object includes stacking a plurality of layers of foil to provide a multi-layered structure, diffusion bonding the plurality of layers together, and shaping the diffusion bonded multi-layered structure to form the object (400).
