  1. 1. Stainless steel plasticity : material modelling and structural applications

    Författare :Anders Olsson; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stålbyggnad; Steel Structures;

    Sammanfattning : The thesis addresses stainless steel in construction with focus on plasticity and shear resistance of welded girders respectively. In the area of plasticity it comprises an account of an experimental study with emphasis on phenomenological observations followed by theorethical modelling. LÄS MER

  2. 2. Passivation of Austenitic Stainless Steel

    Författare :Lena Wegrelius; Chalmers University of Technology; []
    Nyckelord :stainless steel; chloride; molybdenum; passivation; hydrochloric acid; nitrogen; ESCA; dissolution;

    Sammanfattning : The objective of this thesis is to study the corrosion resistance and passivation of high alloyed austenitic stainless steels exposed to hydrochloric acid. The introductory section gives a background to the subject; electrochemical measurements and surface analysis by the ESCA-technique (Electron Spectroscopy for Chemical Analysis). LÄS MER

  3. 3. Plastic Deformation of Duplex Stainless Steel

    Författare :Magnus Nyström; Chalmers University of Technology; []
    Nyckelord :stainless steel; microstructure; plastic zones; impact toughness; anisotropy; prestraining; annealing; fractography; fatigue;

    Sammanfattning : Duplex austenitic/ferritic stainless steels are increasingly used as an alternative to conventional austenitic grades. Main advantages of the duplex grades are good resistance to corrosion cracking and corrosion fatigue in environments that contain chloride. LÄS MER

  4. 4. Simulation of stainless steel tube extrusion

    Författare :Sofia Hansson; Hansson Sofia; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik; Extrusion; finite element method; stainless steel; physically based material model; dislocation density; Simulering av extrusion av rostfria rör;

    Sammanfattning : The simulation of hot extrusion processes is a difficult and challenging problem in process modeling. This is due to very large deformations, high strain rates and large temperature changes during the process. LÄS MER
