Quantitative Metallography of the Age Hardening Precipitate in Superalloys by Replica Electron Microscopy

Source

The application of two quantitative techniques to the measurement of gamma prime size, interparticle spacing, and volume fraction in two commercial heat resistant alloys is discussed. The two methods involve the use of structure and extraction replica electron microscopy and were evaluated for their ease of application and consistency of data using various measuring parameters.
