20. Surface Integrity and Fatigue Performance of Nickel-based Superalloys
Abstract : Due to global warming, the demand for more efficient gas turbines has increased. A way to achieve this, is by increasing the operating temperature of the gas turbine. Therefore, nickel-based superalloys have been developed to withstand these extreme temperatures and loads, especially in the hot sections. READ MORE
