    Sammanfattning : Aluminum alloys are of great importance in the automotive and truck industries due to the weight savings that they can help to achieve. However, the use of such alloys in applications where they are subjected to alternating stresses requires knowledge about their fatigue behavior. LÄS MER

  4. 3. Construction of cooling rig and investigation of cooling sensitivity for aluminum crash alloy

    Master-uppsats, KTH/Materialvetenskap

    Författare :Lars Björk; [2015]
    Nyckelord :quenching; cooling sensitivity; crash performance; aluminum alloy; cooling rates; quenching rates; precipitation on grain boundaries; Mg2Si; cooling rig; cooling equipment; bending angle;

    Sammanfattning : The work presented in this master thesis deal with the issue of quenching, investigation regarding different cooling rates and its effect on the material properties of aluminum alloy in the 6xxx series used for crash purposes in cars, such as crash boxes, beams and other crash relevant parts. Precipitation of Mg2Si due to different cooling rates affects the material properties such as crash performance, thus the aluminum alloy used is sensitive to different cooling rates. LÄS MER
