Abstract
This appendix provides additional information on superalloy microstructures. It includes several micrographs showing metallographic features mentioned in the text but not illustrated elsewhere in the book. It also discusses carbide reactions that occur during heat treating and demonstrates the use of electron vacancy calculations to estimate the resistance of superalloys to the formation of topologically close-packed phases.
