Abstract
The method of consolidating a metallic, metallic and ceramic, or ceramic body in any of initially powdered, sintered, fibrous, sponge, or other form capable of compaction, includes the steps: (a) providing a bed of flowable particles within a contained zone, said particulate primarily including flowable and resiliently compressible carbonaceous particles, (b) positioning said body in said bed, (c) and effecting pressurization of said bed to cause pressure transmission via said particles to said body, thereby to compact the body into desired shaped, increasing its density, (d) said body and bed being at elevated temperatures prior to said pressurization step.

The method of consolidating a metallic, metallic and ceramic, or ceramic body in any of initially powdered, sintered, fibrous, sponge, or other form capable of compaction, that includes the steps:
- (a) providing a bed of flowable particles within a contained zone, said particulate primarily consisting of flowable and resiliently compressible carbonaceous particles, in the form of beads having outwardly projecting nodules thereon, and at least some beads having surface fissures,
- (b) positioning said body in said bed,
- (c) and effecting pressurization of said bed to cause pressure transmission via said particles to said body, thereby to compact the body into desired shape, increasing its density,
- (d) said body and bed being at elevated temperatures prior to said pressurization step.
