A process for vacuum degassing a metal powder within a containment comprising a plurality of gas purging pipes and a plurality of gas evacuation pipes, the process comprising:
- purging with an inert gas through at least one gas purging pipe of the plurality of gas purging pipes;
- and
- evacuating gas in the containment through at least one gas evacuation pipe of the plurality of gas plurality pipes;
- wherein the process comprises an initial gas purge and at least one subsequent gas purge.
A containment for use in hot isostatic pressing, the containment comprising:
- a body sealed at both ends;
- at least one gas purging pipe defining a first portion of a gas passage from outside of the containment to inside of the containment;
- and
- at least one gas evacuation pipe defining a second portion of the gas passage from outside of the containment to inside of the containment;
- wherein the at least one gas purging pipe and the at least one gas evacuation pipe define the gas passage through the containment which extends from the at least one gas purging pipe to the at least one gas evacuation pipe.
