  1. 11. 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. 12. Initial Oxidation of β-NiAl(Pt) Coatings and Model Alloys

    Författare :Henrik Svensson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FIB-SEM; SEM; #946; TEM; Diffusion Coatings; Metal-Oxide Interface; High Temperature Oxidation; Cavities; Platinum; -NiAl;

    Sammanfattning : The aim of this work was to investigate the oxidation properties of NiAl coatings and model materials during high temperature oxidation. One of the important issues was to elucidate the beneficial role of Pt additions. A better understanding of the involved processes provides a key for the further improvement of the coatings performance. LÄS MER

  4. 13. 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

  5. 14. Synthesis and characterisation of Zintl hydrides

    Författare :Thomas Björling; Dag Noréus; Yvonne Andersson; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Zintl hydrides; BaGa2H2; SrAl2H2; SrAlSiH; BaAlSiH; CaAlSiH; SrGa2H2; Chemistry; Kemi; Structural Chemistry; strukturkemi;

    Sammanfattning : The synthesis, structural characterisation and the properties of the Zintl hydrides AeE2H2 and AeAlSiH (Ae = Ba, Ca, Sr; E = Al, Ga, In, Si, Zn) are reported. The first hydride in this class of compounds is SrAl2H2 which was discovered under an experiment by Gingl, who hydrogenated SrAl2 at various temperatures. LÄS MER
