    Abstract

    Nickel superalloys are used to manufacture high temperature rotary engine parts such as high pressure disks in gas turbine engines. In this application high strength at high operating temperatures is required due to the levels of stress and heat the disk must withstand. Additionally, the higher the temperature of a gas turbine engine the more fuel efficient it is, which is desirable for commercial airplane companies.
