    Sammanfattning : The use of waste (or recycled) wood as a fuel in heat and power stations is becoming more widespread in Sweden (and Europe), because it is CO2 neutral with a lower cost than forest fuel. However, it is a heterogeneous fuel with a high amount of chlorine, alkali and heavy metals which causes more corrosion than fossil fuels or forest fuel. LÄS MER

  3. 2. Use of localised techniques to elucidate the influence of process variables on the corrosion of stainless steels

    Sammanfattning : Several factors during steel manufacture and fabrication can alter the passivity and corrosion behaviour of stainless steels. These include alloying, deformation, welding and heat treatments. LÄS MER

  4. 3. Casting and anodising of Al alloys- Alloy design, manufacturing process and material properties

    Författare :Baiwei Zhu; Caterina Zanella; Rajan Ambat; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast aluminium; Semi-solid casting; Anodising; Gjutning av aluminium; semi-solid gjutning; anodisering; komponent; gjutlegering; kisel; järn;

    Sammanfattning : Casting and semi-solid metal (SSM) casting are widely used to manufacture near-net-shape components of Al-Si alloys in the automotive and electronic industries. In such applications, casting components need to meet the combined requirements of good mechanical properties and corrosion and wear resistance. LÄS MER

  5. 4. Stacking fault energy and deformation behaviour of austenitic stainless steels: a joint theoretical-experimental study

    Författare :Dávid Sándor Molnár; Levente Vitos; Göran Engberg; Guocai Chai; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; austenitic stainless steel; deformation properties; stacking fault energy; electron backscatter diffraction; ab initio; Teknisk materialvetenskap; Materials Science and Engineering; Steel Forming and Surface Engineering;

    Sammanfattning : Austenitiska rostfria stål är främst kända för sin exceptionella korrosionsbeständighet. De har en ytcentrerad kubisk (FCC) struktur som stabiliseras genom att nickel, mangan eller kväve tillsätts till Fe-Cr legeringen. Fe-Cr-Ni-systemet kan utökas ytterligare genom tillsats av andra element såsom Mo, Cu, Ti, C, etc. LÄS MER

  7. 5. Generalised stacking fault energy and plastic deformation of austenitic stainless steels

    Författare :Dávid Sándor Molnár; Levente Vitos; Guocai Chai; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stacking fault energy; stainless steel; plasticity; deformation; ab initio; Teknisk materialvetenskap; Materials Science and Engineering; Steel Forming and Surface Engineering;

    Sammanfattning : Austenitic stainless steels are primarily known for their exceptional corrosion resistance. They have the face centred cubic (FCC) structure which is stabilised by adding nickel to the Fe-Cr alloy. The Fe-Cr-Ni system can be further extended by adding other elements such as Mn, Mo, N, C, etc. in order to improve the properties. LÄS MER
