Title: Metal consolidation process employing microwave heated pressure transmitting particulate

Abstract: A method of consolidating metal powder to form an object, includes: a) pressing the powder into a preform, and preheating the preform to elevated temperature, b) providing flowable pressure transmitting particles and transmitting microwaves into the particles to heat same, and providing a bed of the flowable and heated pressure transmitting particles, c) positioning the preform in such relation to the bed that the particles substantially encompass the preform, d) and pressurizing the bed to compress said particles and cause pressure transmission to the preform, thereby to consolidate the preform into a desired object shape.
