Introduction
The working temperature of a jet engine is limited by the temperatures that its component materials can tolerate. Thus, there is a ongoing need for the development of jet-engine materials that can operate at increasingly higher temperatures. Nickel superalloys have been established as disc and blade materials, as they meet the requirements for such components. The combination of high temperatures and high stresses in blades make them susceptible to creep, and the interactions of creep and fatigue can seriously affect components’ life. In addition, mixed-mode loading produces stress-states that...
