  1. 11. Orientation dependant grain boundary diffusion in polycrystals

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Hållfasthetslära

    Author : Kevin Hult Blixt; [2020]
    Keywords : Technology and Engineering;

    Abstract : Grain boundary diffusion in polycrystals is of importance in industrial applications as it often, to a large degree, dictates the effective rate of diffusion in polycrystals. For impurity diffusion the enrichment of impurities within the material will in turn change the material properties, such as ductility and fatigue rates. READ MORE
