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

    Författare :Svjetlana Stekovic; Torsten Ericsson; Hael Mughrabi; Linköpings universitet; []
    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; Materials science; 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

  3. 2. Property measurements towards understanding process phenomena

    Författare :Riad Abdul Abas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The main objective of this industrially important work was to gain an increasing understanding of the properties of materials such as CMSX-4 nickel base super alloy, mould powder used in continuous casting of steel and coke used in blast furnace, with special reference to the thermal diffusivities. The measurements were carried out in a wide temperature range, solid, liquid, glassy and crystalline states. LÄS MER

  5. 4. Aluminide Diffusion Coatings for Ni Based Superalloys. Coating and Oxide Microstructure

    Författare :Johan Angenete; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; aluminide diffusion coatings; nickel based superalloys; SEM; TEM; high temperature oxidation;

    Sammanfattning : This thesis reports on investigations of high temperature oxidation resistant aluminide diffusion coatings for Ni based superalloys. Such coatings basically consist of a .BETA.-NiAl layer at the surface of the . LÄS MER

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

    Författare :Svjetlana Stekovic; Linköpings universitet; []
    Nyckelord :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
