ABSTRACT:
A method for producing compacted, fully dense articles from atomized tool steel alloy particles by placing the particles in an evacuated, deformable container, and isostatically pressing the particles at an elevated temperature to produce a precompact having an intermediate density. The precompact is heated to a temperature above the elevated temperature used to produce the precompact. The precompact is isostatically pressed to produce the fully-dense article.
