  1. 1. Effects of natural aging and low strain-rate on mechanical properties of aluminium alloy sheets used in automotive industry

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Amirhossein Gholami; Ali Abedisamarin; [2024]
    Nyckelord :Ageing. AA6014. AA6016;

    Sammanfattning : These days, lightweight materials such as aluminum alloy sheets, especiallythose in the AA6xxx series, are in high demand for use inthe automotive industry. During natural aging, the properties of aluminummay undergo significant changes due to the diffusion of atomswithin the crystal structure, impacting the strength and formabilityof aluminum sheets.

  7. 5. Jämförelse av torr bearbetning och minimalsmörjningseffekter på fräsning av austenitiskt rostfritt stål

    M1-uppsats, Högskolan i Gävle/Maskinteknik

    Författare :Adam Norell; Darav Hajo; [2023]
    Nyckelord :MQL; milling; stainless steel; tool wear; MQL; fräsning; rostfritt stål; verktygsförslitning;

    Sammanfattning : Fräsning och annan intermittent skärande bearbetning ger upphov till termisk utmattning av skärverktyg. Problemet med termiska sprickor blir större vid bearbetning av värmehållfasta material som austenitiskt rostfritt stål eftersom värmeväxlingarna i skärverktyget blir mer extrema. LÄS MER
