Method for compacting high alloy steel particles

摘要

A method for producing compacted, fully dense articles from atomized tool steel alloy particles by placing the particles in a 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.
