Abstract : Superalloy processing, and hot isostatic pressing (P) is near-net shape is the most cost-effective method of superalloy powder consolidation. However, as HIP superalloys have ben plagued by poor mechanical properties, which can be ascribed to materials cleanliness and to prior particle powder boundaries (PPB). The solution to the first problem is the policing of the process, and the solution to the second problem is more technical and pivots about altering the deformation mechanism comprising HIP densification to minimize PPB.
