  4. 3. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy

    Master-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Anton Rolseth; [2023]
    Nyckelord :Aluminium alloys; sheet metal forming; grain boundary segregation; recrystallization; Zener pinning; casting; rolling;

    Sammanfattning : Aluminium alloys have the possibility to be infinitely recycled. By only generating 5% of the emissions compared to primary aluminium, great CO2 savings can be made. One of the issues in manufacturing components entirely from post-consumer scrap is the presence of trace elements and impurities. Such elements can be Fe, Cu, Cr, P and Pb. LÄS MER
