    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

  2. 2. Surface Integrity of Broached Inconel 718 and Influence of Thermal Exposure

    Author : Zhe Chen; Ru Lin Peng; Johan Moverare; Sten Johansson; Magnus Hörnqvist; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER;

    Abstract : Inconel 718 is a nickel-based superalloy that is extensively used as a disc material in gas turbine engines. The service life of gas turbine discs is normally governed by the modes of material degradation and fatigue failure since they work mostly at high temperatures and are subjected to cyclic mechanical loadings.
