Abstract

During heat treatment of Nimonic 108 turbine blades, white patches were formed on the aerofoil surface. Microstructure of the section through these patches indicated presence of chromium carbide precipitated along the grain boundaries. This is due to diffusion of carbon from the surface, at a high temperature for a prolonged time.
