Nickel based Super Alloys Properties and Applications
Nickel based Super Alloys Properties and Applications Nickel-Based Superalloys The nickel-based superlloys are often the material of choice for high-temperature structural applications, particularly when resistance to creep and/or fatigue is needed and the risk of degradation due to oxidation and/or corrosion is severe. Nickel-based superalloys were developed and have been improved over the past 50 years for applications involving stringent elevated-temperature operating conditions, such as those experienced by components of gas turbine engines . Due to their good properties at elevated temperatures, nickel base superalloys have been widely used for aerospace, power generation, and automotive high temperature applications since their emergence in the 1950s. Nickel-base superalloys are corrosion resistant high temperature alloys typically used at service temperatures above 500°C. They usually contain significant amounts of up to 1...
