Abstract:
A method for creating a metallurgic component comprises creating a thin-walled container corresponding to a shape of the metallurgic component from a metal. If powder metal is not already in the container (depending on a method of creating the container), the thin-walled container is filled with powder metal. A quick-can device is fixed to the thin-walled container, and the powder metal is consolidated inside the thin-walled container (e.g., in a hot isostatic press). During consolidation, pressure within the thin-walled container is monitored and a desired pressure differential between an inside of the thin-walled container and an outside of the thin-walled container is maintained by the quick-can device.
