   Abstract : Iron aluminides are candidate materials for a sustainable society since they are composed of abundant metals and have excellent corrosion properties in combination with high specific strength. However, there are some drawbacks that limit the practical use, e.g. low RT ductility and a drop in strength at high temperature. READ MORE

4. 2. A theoretical study of magnetism and its extension to finite temperatures in random alloys

   Author : Fan Pan; Lars Bergqvist; Richard Evans; KTH; []
   Keywords : Fysik; Physics;

   Abstract : This work presents new theoretical developments of atomistic spin simulations of magnetic materials at finite temperatures. Special focus is put on the description of longitudinal magnetic fluctuations and the application in random transition metal alloys. READ MORE

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

   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
