The method uses the inclusion of reactive materials mixed into pressure-transmitting mold materials and into the powder to be consolidated to contribute to in-situ materials modification including purification, chemical transformation, and reinforcement. The method also uses encapsulation of the mold in a sealed container to retain the mold material in position, and to exclude air and contaminants.Field of SearchAddition of fugitive materialSpecific pressure or lack or pressure recited Heat and pressure simultaneously to effect sintering Vacuum VACUUM TREATMENT OF WORK With destruction of pattern or mold to dissociate Forming mold from fluent material Utilizing a flexible, deformable, or destructable molding surface or material Removing mold by destruction Utilizing particular mold material Bulk deposition of particles by differential fluid pressure | |
