<p>This is a powder metallurgy process for producing a plurality alloy article, for example such as molds and dies. It comprises producing a ceramic core having a surface corresponding to the desired configuration of the mold or die, placing the core in a container and filling the container and surrounding the core with a particle charge of the alloy from which the mold is to be made, heating the charge to compacting temperature and compacting the charge by the application of isostatic pressure to a final density. Thereafter, the ceramic core is removed to expose the corresponding compacted surface of the alloy charge, which is configurated in accordance with the surface of the core and constitutes the desired mold or die surface.</p> |
