  1. 6. Oxidation and degradation of nickel-base alloys at high temperatures

    University essay from KTH/Materialvetenskap

    Author : Frans Palmert; [2009]
    Keywords : oxidation; nickel; nickel-base; superalloy; PWA1483; IN792; turbine; cyclic; spalling; hardness; gamma prime; coarsening; degradation; microstructure;

    Abstract : This master’s thesis work is a study of oxidation and degradation of nickel-base alloys at high temperatures. The materials studied are designed for use in critical gas turbine components such as turbine blades and vanes. Some of the alloys are used today, whereas others have not yet entered commercial application. READ MORE

  3. 7. Constitutive modelling of the nickel base superalloy IN718; a preparatory study

    University essay from Hållfasthetslära

    Author : David Gustafsson; [2008]
    Keywords : material model; superalloy; cyclic behaviour; Armstrong-Fredrick; LS-DYNA; FORTRAN;

    Abstract : One of the limiting factors in gas turbine design is the allowable metal temperatures and loads in critical components. Specially designed superalloys are used when the conditions are most severe. One of these superalloys is Inconel 718. READ MORE
