ABSTRACT:
An apparatus for use in hot pressing metal alloy foils, such as by HIP, directly from metal alloy powders. The invention is a metal container with a cavity having near-net shape of a thin metal foil. The cavity may be lined with a diffusion inhibiting material, so as to inhibit the interdiffusion between the metal container and the metal alloy powder during hot pressing. The apparatus also may include an integrally formed orifice for evacuating the metal container.
