Isostatic and pseudoisostatic compaction

Abstract

This chapter discusses isostatic and pseudoisostatic compaction. In cold isostatic pressing, powder is compacted in a deformable container ideally in a pressure vessel under isostatic triaxial compression. Forming processes illustrated are wet bag isostatic tube compaction, wet bag pressing of internal thread, dry bag isostatic pressing with powder filling in press, dry bag isostatic pressing with external powder fill, and rubber isostatic pressing. In hot isostatic pressing (HIP), powders are brought into shape and simultaneously consolidated to full density. Cladding by HIP and design of the pseudo-HIP process are illustrated. The STAMP process focuses on time reduction for consolidation. Rapid omnidirectional compaction (ROC) is a near-net shaping technology using a similar way of consolidation as the STAMP process. The chapter also illustrates the various forms of fluid die and preform. The Ceracon process aims at consolidation to full density of porous powder metallurgical preforms as near-net shapes. The ceramic mold process allows the manufacture of fully dense net shapes of high intricacy and irregular geometry.
