Microstructure, Processing, Characteristics, and Engineering Application Specifically of Iron-based Superalloys

Uzma Hira, Yousra Akram

The struggle for finding materials with greater thermal stability, high strength, creep resistance, resistance to oxidizing environments, and corrosion, provides the basic impetus behind the creation of superalloys. Due to their possession of all these qualities, superalloys have brought innovations in jet and marine turbine engine applications because they possess extraordinary stability even at elevated temperatures in contrast to most of the materials used in the past. High fractions of the melting point can be used in superalloys, and this attribute has made them suitable for use in high-temperature applications. Superalloys possess special protective coatings responsible for their anti-corrosive characteristics and mechanical properties which remain stable at high temperatures, making it possible to manufacture their products under high stress. This chapter will further elaborate on the microstructure, processing, characteristics, and engineering application specifically of iron-based superalloys. It also shows the prospects and difficulties that may arise in superalloys machining.
