  2. 1. The Precipitation and Deformation Behaviour of Superaustenitic Stainless Steel

    Author : Stefan Heino; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; precipitation; low cycle fatigue TEM; slip behaviour; superaustenitic stainless steel; EDS; cyclic deformation; HAZ; tungsten; molybdenum;

    Abstract : The present study concerns the precipitation behaviour and the deformation characteristics of a superaustenitic stainless steel with composition Fe-24Cr-22Ni-7.3Mo-0.5N (wt%). Regarding precipitation, also materials with Mo partially replaced by W have been studied. READ MORE

  4. 2. A Model for Simulation of Fiber Suspension Flows

    Author : David Hammarström; KTH; []
    Keywords : rheology; fiber; suspension; CFD; model; wall; slip; turbulence;

    Abstract : The fiber suspensions in the production line from wood topaper are subjected to many types of chemical and mechanicalprocesses, in which the flow of the suspension is of vitalimportance. The flow of the suspension determines the degree ofuniformity of the fibers through the processing, which inreturn affects the properties of the fiber suspension. READ MORE

  5. 3. Cyclic behaviour of carburized steel

    Author : Lennart Magnusson; Yngve Bergström; Linköpings universitet; []
    Keywords : ;

    Abstract : The fatigue properties of carburized low alloyed steel have been investigated. The tests in axial fatigue showed that surface carbon below 0.8% and low amounts of retained austenite are advantageous. In bending fatigue the effects of tempering and of surface condition were studied. READ MORE

  6. 4. Structural Behaviour of Deteriorated Concrete Structures

    Author : Kamyab Zandi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FE analysis; concrete; stirrup; corrosion; bond; pull-out test; frost;

    Abstract : A growing concern for better assessment of existing concrete structures has revealed a need for improved understanding of the structural effects of deterioration. The two most common causes of deterioration in concrete structures are freezing of the concrete and corrosion of the reinforcement. READ MORE

  7. 5. High-Temperature Behaviour of Austenitic Alloys : Influence of Temperature and Strain Rate on Mechanical Properties and Microstructural Development

    Author : Mattias Calmunger; Sten Johansson; Guocai Chai; Johan Moverare; Göran Engberg; Linköpings universitet; []
    Keywords : ;

    Abstract : The global increase in energy consumption and the global warming from greenhouse gas emission creates the need for more environmental friendly energy production processes. Biomass power plants with higher efficiency could generate more energy but also reduce the emission of greenhouse gases, e.g. CO2. READ MORE
