Corrosion Fatigue of AA6082 Aluminium Alloy: The Effects of Coating and Ti Additions
Fredrikstad, Joakim Enger (Master thesis, 2019)Effektene av anodisering og organisk belegg (KTL) på korrosjonsutmattingsegenskapene til en ekstrudert AA6082 aluminiumslegering ble undersøkt. Ubelagte og anodiserte prøver med ekstra Ti i legeringen ble også testet. En ... -
Data Pre-processing and Sensor-Fusion for Multivariate Statistical Process Control of an Extrusion Process
Westad, Frank; Lodgaard, Lars; Pedersen, Torbjørn (Peer reviewed; Journal article, 2023)In most manufacturing processes, data related to a product are collected across several process steps. Ensuring good data quality is essential for subsequent process modeling, monitoring, and control. Although data for a ... -
Influence of local microstructural variations on the bendability of aluminium extrusions: experiments and crystal plasticity analyses
Frodal, Bjørn Håkon; Lodgaard, Lars; Langsrud, Yngve; Børvik, Tore; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2023)The bendability of extruded profiles of an age hardenable aluminium alloy is investigated using mechanical tests on flat tensile specimens and bending specimens. Two profile geometries are considered, where the profiles ... -

Stress Corrosion Cracking in an Extruded Cu-Free Al-Zn-Mg Alloy
Lervik, Adrian; Walmsley, John Charles; Lodgaard, Lars; Marioara, Calin Daniel; Johnsen, Roy; Lunder, Otto; Holmestad, Randi (Peer reviewed; Journal article, 2020)Stress corrosion cracking (SCC) in Cu-free Al-Zn-Mg (7xxx) aluminium alloys limits its use in many applications. In this work, we study in detail the microstructure of a peak and slightly overaged condition in an AA7003 ... -
The effect of cooling rate from solution heat treatment on ductility in Al-Mg-Si crash box alloys
Lesjø, Martin Bakken (Master thesis, 2022)Effekten på duktilitet av kjølehastighet fra innherding av Al-Mg-Si-legeringer er undersøkt. Tre forskjellige legeringer ble avkjølt med fire forskjellige kjølemetoder. Disse var kaldt vann, kokt vann, luft med konveksjon ...
