  1. 1. Micromechanics of oxides - From complex scales to single crystals

    Författare :Anand Harihara Subramonia Iyer; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cr2O3; oxide scales; micromechanical testing; fracture; electron microscopy;

    Sammanfattning : Protective oxide scales shield high temperature materials from corrosion, thus ensuring safety and long material life under adverse operating conditions. Cracking and spallation of such scales can lead to fatigue crack initiation and expose the material to further oxidation. LÄS MER

  3. 2. Oxidation induced failure of superalloys: High temperature crack growth and oxide scale properties

    Författare :Anand Harihara Subramonia Iyer; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; micromechanical testing; crack growth; Nickel superalloys; scanning electron microscopy; focused ion beam microscopy;

    Sammanfattning : Gas turbine materials are designed to work in extreme environments in high temperature with an oxidising environment and variable mechanical loading. The study of high temperature fatigue properties of these materials is therefore important. LÄS MER
