摘要
A method of densifying a metallic powder comprises the steps of cryomilling the metallic powder to produce a nanocrystalline metallic powder; degassing the nanocrystalline metallic powder; preforming the degassed nanocrystalline metallic powder for a subsequent equal channel angular pressing (ECAP) process according to the metallic powder being processed; and equal channel angular pressing (ECAP) the preformed degassed nanocrystalline metallic powder at a predetermined temperature and pressure.
