Densification Behaviour of Particle-Reinforced Superalloy Powder During Hot Isostatic Pressing

  • Conference paper
Hot Isostatic Pressing— Theory and Applications

Abstract

In this paper understanding of the role of inclusions in the consolidation process of powder composite is attempted. A nickel base superalloy powder was mixed with alumina particles and consolidated by hot isostatic pressing. Densification kinetics were estimated from interrupted HIP tests, and compacted specimens were observed by microscopy. Simple compression tests were also performed at high temperature on dense samples. From these results explanations for the retardation in densification due to the inclusions are suggested.
