    Sammanfattning : The integrated steel-making plants in Sweden contributed with approximately 8 % of the total CO2 emissions in the country in 2011. A major contributor to these emissions is the combustion of fossil fuels in different process units. Therefore, it is essential to reduce emissions by limiting the fossil fuels consumption in the steel industry. LÄS MER

  4. 4. Magnetic Resonance Imaging of Human Brown Adipose Tissue : Methodological Development and Application

    Sammanfattning : Brown adipose tissue (BAT) is a thermogenic organ with the main human depot located in the cervical-supraclavicular (sBAT) region. BAT is proposed as a potential therapeutic target for obesity and diabetes. LÄS MER

  5. 5. On the analysis of cast structure and its changes during hot working of forging ingots

    Författare :Jan Sarnet; Hasse Fredriksson; Alec Mitchell; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Forging ingots are hot worked to consolidate structural imperfections and refine the microstructure. Possible imperfections are segregations, porosities, cracks, and inclusions. In this thesis, techniques and methods for the characterisation of behaviour and properties of ingots and forgings. LÄS MER
