The Analysis of Ceramic Inclusions in P/M Rene' 95 Superalloy Powder Particles

Water Elutriation method was applid to determin the content of ceramic inclusions in P/M Rene'95 powder paticles quantitatively. The study proved that is quite adequate for the analysis of ceramic inclusions in superalloy powders, which can vary either in size or in morphology. Several parameters concerning with the ceramic inclusions were determined. Furthermore, the compositions and the morphology of the ceramic inclusions are discussed as well.
