  1. 11. High-Temperature Behaviour of Austenitic Alloys : Influence of Temperature and Strain Rate on Mechanical Properties and Microstructural Development

    Författare :Mattias Calmunger; Sten Johansson; Guocai Chai; Johan Moverare; Göran Engberg; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The global increase in energy consumption and the global warming from greenhouse gas emission creates the need for more environmental friendly energy production processes. Biomass power plants with higher efficiency could generate more energy but also reduce the emission of greenhouse gases, e.g. CO2. LÄS MER

  4. 13. Surface Integrity and Fatigue Performance of Nickel-based Superalloys

    Författare :Zhe Chen; Ru Peng; Johan Moverare; Sten Johansson; Manuel François; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : 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. LÄS MER

  5. 14. Surface Integrity of Broached Inconel 718 and Influence of Thermal Exposure

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

    Sammanfattning : 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.
