  3. 3. Low Cycle Fatigue and Thermo-Mechanical Fatigue of Uncoated and Coated Nickel-Base Superalloys

    Detta är en avhandling från Institutionen för ekonomisk och industriell utveckling

    Författare :Svjetlana Stekovic; Torsten Ericsson; Hael Mughrabi; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AMDRY997; CMSX-4; SCB; Thermo-Mechanical Fatigue; Coatings; Gas Turbine; IC1; IC3; IN792; Low Cycle Fatigue; Nickel-Base Superalloys; RT22; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Sammanfattning : High strength nickel-base superalloys have been used in turbine blades for many years because of their superior performance at high temperatures. In such environments superalloys have limited oxidation and corrosion resistance and to solve this problem, protective coatings are deposited on the surface. LÄS MER

  4. 4. Isothermal low cycle fatigue of uncoated and coated nickel-base superalloys

    Detta är en avhandling från Institutionen för ekonomisk och industriell utveckling

    Författare :Svjetlana Stekovic; Linköpings universitet.; Linköpings universitet.; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : High strength nickel-base superalloys have been used in turbine blades for many years because of their superior performance at high temperatures. However, the superalloys have limited oxidation and corrosion resistance and to solve this problem, protective coatings are deposited on the surface of the superalloys. LÄS MER

  5. 5. Synthesis of Transition Metal Aluminides from Elemental Powder Mixtures

    Detta är en avhandling från Lund University (Media-Tryck)

    Författare :Hossein Sina; Lund University.; Lunds universitet.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminides; Intermetallics; Powder Metallurgy; Reactive Sintering; Combustion Synthesis; Thermal Analysis; DSC; Onset temperature; Phase evolution; SEM; EDS; XRD;

    Sammanfattning : Structural components such as those used in gas turbines for energy conversion applications, are subjected to high loads at elevated temperatures. In order to ensure that the components survive under these conditions for a sufficiently long time, it is imperative to select materials with good high temperature properties like strength and corrosion resistance.
