Abstract

Specific anodic dissolution procedures are detailed for the quantitative separation of carbides, topologically close-packed (TCP) phases, and γ′ from high temperature nickel-base superalloys. Reagents are suggested for the isolation of phases from mixed anodic deposits through selective dissolution techniques. Methods for the chemical analysis of separated phases are discussed. The application of phase separation to specific metallurgical studies is described in detail.
