The effect of thickness and compaction on the recovery of aluminium in recycling of foils in salt flux
Philipson, Harald (Master thesis, 2020)I Norge förbränns mer än 40 000 ton aluminiumförpackningar årligen. Återvinning av denna mängd aluminiumförpackningar skulle spara 1,5 TWh energi och hundratusentals ton av koldioxidutsläpp. Det mycket svårare att återvinna ... -
The Mechanism Behind the Oxidation Protection of High Mg Al Alloys with Beryllium
Smith, Nicholas; Kvithyld, Anne; Tranell, Gabriella (Journal article; Peer reviewed, 2018)The addition of beryllium to Al-Mg alloys is known to cause a dramatic decrease in oxidation; however, the mechanism behind this protective effect is not yet fully understood. To aid in finding an alternative to the toxic ... -
Thermal Decoating of Aluminium Scrap
Kvithyld, Anne (Dr. ingeniøravhandling, 0809-103X; 2003:6, Doctoral thesis, 2003)A major problem in the recycling of aluminium is the presence of contaminants in the purchased scrap. Future plants may handle part of this challenge by installing a delacquering/decoating unit. This thesis attempts to lay ... -
Thermal De‑coating Pre‑treatment for Loose or Compacted Aluminum Scrap and Consequences for Salt‑Flux Recycling
Vallejo-Olivares, Alicia; Høgåsen, Solveig; Kvithyld, Anne; Tranell, Gabriella (Peer reviewed; Journal article, 2022)In aluminum recycling, thermal de-coating pre-treatments remove moisture and organic contamination before re-melting. If the scrap is compacted into bales or briquettes before the thermal treatment and re-melting processes, ... -
XPS Examination of the Oxide-Metal Interface of an Aluminum-Magnesium Alloy Containing Beryllium
Smith, Nicholas; Kvithyld, Anne; Tranell, Gabriella (Chapter, 2018)The addition of beryllium to high magnesium aluminum alloys has long been known to cause a significant decrease in the rate of alloy oxidation. A clear understanding of the fundamental mechanism behind this effect is still ...
