Consolidation of Encapsulated Compacts

When metal powder is consolidated via HIP, encapsulation is required to act as a barrier between the high-pressure gas and the powder to provide the differential force required to create the plastic deformation of the powder. Powder is typically placed in a container or envelope made of metal or glass to a specified shape larger than final desired size. There are three main components to producing a HIP-encapsulated P/M part, namely: powder manufacturing and processing, container manufacturing, and compact manufacturing.
