6. 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

8. Computational modeling of oxygen-assisted fracture in nickel-based superalloys
Abstract : Nickel-based superalloys are a commonly used material in applications where high strength is required at high temperatures. A typical such example is jet engines and, in the case of polycrystalline nickel-based superalloys, components like turbine disks. READ MORE

9. Fatigue life prediction of additively manufactured ductile nickel-based superalloys : Constitutive and crack initiation modelling
Abstract : This dissertation was produced at the Division of Solid Mechanics at Linköping University, and is the final result of a project that included mechanical testing and modelling of an additively manufactured ductile nickel-based superalloy.The main objective of the work presented in this thesis was to investigate and model the cyclic behaviour and the fatigue life behaviour of an additively manufactured ductile nickel-based superalloy, with emphasis on modelling the stabilised material behaviour, by which fatigue life predictions can be based upon.

10. Weld Cracking in Precipitation Hardening Ni-based Superalloys
Abstract : Manufacturing of hot structural components for aero engines requires the materials being used to be weldable. The high demands on strength and temperature resistance make nickel based superalloys the material of choice for this application. READ MORE
