The parts then go through inspections, heat treatment, or densification by the hot isostatic press (HIP) method.
Microshrinkage of the castings cannot be avoided as the material solidifies, but if it can be restricted to the region around the centerline of the part then the HIP process may be able to eliminate it.
Compaction of the powder alloy into a consolidated form relies on hot isostatic press- ing to its nearly full density, followed by hot extrusion.
During the HIP procedure, the powder in the container is heated either to a tem- perature above the solvus or below it, depending on the required size of the grain in the final product.
Many components can be used after the HIP and the subsequent heat treatment process.
