Stress corrosion cracking (SCC) is a major damage mechanism on power generating Low Pressure (LP) turbines. Heat treatment condition was identified as the primary cause of premature cracking/failure of turbine blades in power plants.

The objective of this research is to investigate the influence of heat treatment on the microstructure, mechanical properties and stress corrosion cracking properties of FV520B stainless steel. In this way, a better understanding of the SCC process can be achieved with identification of the dominant failure mechanisms and according appropriate strategies for prevention.
