ABSTRACT:
A [container] method for hot consolidating powder of metallic and non-metallic composition and combinations thereof by the application of heat and pressure [wherein the] to a thick-walled and regularly shaped container [includes] having a mass of container material which is substantially fully dense and incompressible and is capable of plastic flow at [pressing] conventinal compaction temperatures, a cavity of [a predetermined] an irregular shape formed within the mass for receiving a quantity of powder, the mass including walls around the cavity of sufficient thickness so that the exterior surface thereof does not closely follow the contour of the cavity whereby, upon the application of heat and pressure to the container, the mass acts like a fluid to apply hydrostatic pressure to the powder contained in the cavity.
