PRESSURIZED ANNEAL OF CONSOLIDATED POWDERS

摘要

Systems and methods for producing a dense, well bonded solid material from a powder may include consolidating the powder utilizing any suitable consolidation method, such as explosive shockwave consolidation. The systems and methods may also include a post-processing thermal treatment that exploits a mismatch between the coefficients of thermal expansion between the consolidated material and the container. Due to the mismatch in the coefficients, internal pressure on the consolidated material during the heat treatment may be increased.

1. A method for preparing a bulk material comprising the steps of:
placing a powder into a container; using a consolidating method to convert said powder into a compact that is a solid; and applying a thermal treatment to said container and compact, wherein the thermal treatment enhances densification and inter-particle bonding of the compact.
