A method of consolidating a body in any of initially powdered, sintered, fibrous, sponge, or other form capable of compaction, including the steps: providing a bed of flowable particles within a contained zone, the particulate including flowable and resiliently compressible carbonaceous particles; positioning the body in the bed, to be surrounded by the particles; effecting pressurization of the bed to cause pressure transmission via the particles to said body, thereby to compact the body into desired shape, increasing its density; the particles being heated to elevated temperature prior to compacting of the body into desired shape; and the heating of the particles being effected by passing electric current through same, with heat generated in the particles also to be transferred to the body. The electrically heated mass of particles may be fluidized; the particles may consist of graphite; and the body may consist of metal, ceramic, or synthetic resin.

A method of treating a preform consisting essentially FeNeB alloy particles to produce a magnet having superior magnetic properties, the steps: (a) removing O. sub. 2 from the preform and applying an O. sub. 2 resistant coating to the preform surface, or removing O. sub. 2 and maintaining an O. sub. 2 -free environment, (b) heating the coated preform to elevated temperature and in a non-oxidizing atmosphere, to facilitate subsequent bonding of the particles during their consolidation, (c) providing a consolidation zone containing a grain bed and transferring the heated and coated or uncoated preform to said zone to be embedded in the grain bed, (d) applying pressure to the grain bed sufficient to be transferred via the bed and to the heated preform, thereby to consolidate the preform.

A method of consolidating metal powders selected from the group consisting essentially of aluminum, aluminum alloys, and aluminum metal matrix composites includes: pressing the powder into a preform, and preheating the preform to elevated temperatures; providing a bed of flowable pressure transmitting particles; positioning the preform in such relation to the bed that the particles encompass the preform; and pressurizing the bed to compress the particles and cause pressure transmission via the particles to the preform, thereby to consolidate the body into desired shape. Typically, the metal powder has surface oxide, and such pressurizing is carried out to break up, partially or fully, the surface oxide.

A method of forming a deformable body to desired shape includes the steps (a) providing a bed of flowable particles within a contained zone, (b) relatively positioning said particles adjacent one side of said body, (c) and pressuring said bed to cause pressure transmission via said particles to said body, thereby to deform the body into desired shape.
