Abstract

A method and container for hot isostatic compacting of powder metallurgy charges in a sealed container wherein the container may be both easily removed from the charge after compacting and preserved for subsequent reuse; this is achieved by providing a separating medium between the container interior and the powdered metal charge to prevent bonding during hot isostatic compacting, and removing the compacted charge from the container by introducing fluid under pressure to the container interior to expand the same away from the compacted charge and then providing an opening in the container, preferably at the end thereof, through which the compact is withdrawn.
