  2. 1. Multicomponent diffusional reactions in tool steels : Experiment and Theory

    Author : Greta Lindwall; Malin Selleby; Karin Frisk; John Ågren; Carelyn Campbell; KTH; []
    Keywords : hot-work tool steel; precipitation hardening; DICTRA; coarsening; mobilities; CALPHAD; cobalt; PM tool stees; nitrogen; compound materials;

    Abstract : Many phenomena determining the microstructure of a tool steel and consequently the properties of the material, are governed by multicomponent diffusion. The diffusion driven reactions that take place during, for example, tempering of a hot-work tool steel or when the microstructure develops during hot isostatic pressing of cold-work tool steel, are dependent on the types and amounts of alloying elements.

  5. 3. Performance of High-temperature Coatings : Oxidation and Interdiffusion

    Author : Xiaoyu Sun; Ru Lin Peng; Johan Moverare; Xin-Hai Li; Lindwall Greta; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coating; diffusion; phase transformation; oxidation;

    Abstract : The use of aluminiferous coatings profoundly improves the service life of superalloys but leads to the microstructural degradation of superalloys and thus the loss of mechanical properties. To solve this trade-off, two strategies were employed in this research. READ MORE
