• Charge weld evolution in hollow aluminum extrusion: Experiments and modeling 

      Sariyarlioglu, Eren Can; Negozio, Marco; Welo, Torgeir; Ma, Jun (Peer reviewed; Journal article, 2024)
      Charge welds occur in billet-to-billet extrusion processes due to the transition between successive billets. The material in this transition zone is typically characterized by substandard mechanical properties. In industrial ...
    • Effect of Die Design on Charge Welds in Aluminium Extrusion 

      Sariyarlioglu, Eren Can; Negozio, Marco; Ma, Jun; Welo, Torgeir (Chapter, 2023)
      Aluminium extrusions are used in more and more applications in different industrial fields, due to their properties and productivity. However, in-process scrap produced in aluminium extrusions needs to be reduced to increase ...
    • On the mechanisms of charge weld evolution in aluminum extrusion 

      Sariyarlioglu, Eren Can; Welo, Torgeir; Ma, Jun (Journal article; Peer reviewed, 2024)
      This study aims to provide new insights into the governing mechanisms of material property evolution within the charge weld zone in the hot extrusion process of aluminum profiles. A set of 6xxx series aluminum alloy tubular ...
    • Prediction of longitudinal seam weld quality in multi-chamber aluminium extrusion 

      Sariyarlioglu, Eren Can; Welo, Torgeir; Ma, Jun (Journal article; Peer reviewed, 2024)
      In the extrusion of complex multi-chamber profiles, the longitudinal seam (L-seam) weld quality is significantly affected by the thermo-mechanical history and the ‘local’ formation conditions under which the weld is produced ...
    • Simulation Validation of Extruded Aluminium Quenching 

      Vang, Petter (Master thesis, 2023)
      Denne masteroppgaven ser på å validere simuleringene gjort i programvaren QForm som er laget for å simulere forming av varmt metall, og spesielt ekstrudering og kjøle simuleringer. Denne valideringen vil bli gjort ved å ...
