ABSTRACT:
A method of concurrently compacting and bonding a plurality of solid particles together including combining particles with a thermobonding agent, placing the particle-agent combination in a die having a desired shape, and applying compaction pressure to the particles while concurrently applying sufficient ultrasonic energy to the particles to densify the particles and thermally activate the thermobonding agent.
