  2. 11. Experimental Studies of Deformation Structures in Stainless Steels using EBSD

    Author : Karin Yvell; Annika Borgenstam; Peter Hedström; Göran Engberg; Johan Moverare; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EBSD; Austenitic stainless steels; Duplex stainless steel; In situ tensile test; Grain boundaries; Grain rotation; Grain size distribution; Texture; Strain hardening; Structure-property relationship; High strain rate; Wire rod rolling; Roll forming; Steel Forming and Surface Engineering; Stålformning och ytteknik;

    Abstract : In this thesis, the focus has been the study of deformation structures in stainless steels by using electron backscatter diffraction (EBSD). Via increased knowledge of the evolution of the substructure during deformation, the design and control of the manufacturing process can be improved. READ MORE

  4. 12. High temperature corrosion of low-alloyed and stainless steels: mechanistic study of chlorine-induced corrosion

    Author : Mercedes Andrea Olivas Ogaz; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steels; low-alloyed steels; pre-oxidation; High temperature corrosion; chlorine-induced corrosion;

    Abstract : The global demand on power generation is constantly increasing and so far, also its environmental impact. The environmental impact could primarily be directed to the power generation being based on fossil fuels, giving a net increase of CO2 to the atmosphere when combusted. READ MORE

  5. 13. Martensitic Transformation in Stainless Steels

    Author : Ye Tian; Peter Hedström; Annika Forsberg; David Porter; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : .... READ MORE

  6. 14. 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

  7. 15. Localized corrosion of stainless steels in chlorine dioxide bleach filtrate solutions

    Author : Gustaf Bäck; KTH; []
    Keywords : stainless steels; bleaching; chlorine dioxide; ClO2; localized corrosion; weld oxides; redox potential; potentiostatic polarization; scanning Kelvin probe;

    Abstract : Stainless steels are extensively used in pulp bleach plantsbecause of their high corrosion resistance. However, alsostainless steels might suffer from corrosion and in bleachplants this is a problem. READ MORE
