  1. 1. Emerging mechanisms of FeCrAl(RE) oxide scale formation and permeation from 1st principles

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Vedad Babic; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Alumina forming alloys are important for high temperature applications due to the high stability of the alpha-Al2O3 scale which forms above 900 C. FeCrAl(RE) alloys are alumina formers with small additions of reactive elements, RE e.g. Y, Zr, Hf and Ce, added to improve among others oxidation behavior and scale adhesion. READ MORE

  2. 2. Nitrogen and Water in High Temperature Corrosion - Insights from First Principle Calculations

    University dissertation from Gothenburg : Chalmers tekniska högskola
