  2. 2. Applications of Computational Thermodynamics and Kinetics on Transformations in Stainless Steels

    Author : Sten Wessman; Malin Selleby; Staffan Hertzman; Bosse Sundman; Hannu Hänninen; KTH; []
    Keywords : Stainless Steels; Duplex; Ferrite; Austenite; Computational Thermodynamics; Thermo-Calc; Dictra;

    Abstract : Stainless steels are high-alloyed, usually with multiple components and often also dual matrix phases, as for duplex stainless steels. This make predictions and calculations of alloying effects on equilibria and transformations complicated. READ MORE

  3. 3. Precipitation in Advanced Stainless Steels

    Author : Niklas Holländer Pettersson; Annika Borgenstam; Sten Wessman; Joacim Hagström; Jacques Charles; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : Advanced stainless steels often suffer from complex precipitation behaviour due to the high levels of alloying elements needed to obtain their attractive properties. This demands a correct handling of the material to avoid formation of harmful phases during production, manufacturing and service. READ MORE

  4. 4. Studies on the frost resistance of natural stone

    Author : Lubica Wessman; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; äldre byggnader; kalksten; laboratorieförsök; sten; granit; sandsten; natursten; frostbeständighet; beständighet;

    Abstract : This work deals with the effects of freeze-thawing on the deterioration of some types of natural stone, especially stones frequently used in old buildings in Sweden. Laboratory studies were performed mainly on Gotland sandstone. This stone has been widely used in old buildings in the whole Baltic region, and is often badly deteriorated. READ MORE
