HOT ISOSTATIC PRESSING CONSOLIDATION OF POWDER DERIVED PARTS

Abstract:

A method of forming a metal component from metal powder which includes exposing the metal powder to an inert gas; consolidating the metal powder into a solid metal; followed by exposing the solid metal to a hot isostatic pressing process to form a metal component, wherein the hot isostatic pressing process has one initial compression cycle followed by at least one decompression and recompression cycle.
