• Microstructure in A356/AA6xxx after bimetallic casting with flux coating 

      Bakke, Aina Opsal; Arnberg, Lars; Li, Yanjun (Journal article; Peer reviewed, 2019)
      This work focuses on bimetallic casting between A356 alloy melt and profiles of AA6xxx wrought aluminum alloys through a gravity casting process, with the aim to improve the component's mechanical properties. However, ...
    • Permanent effect of a cryogenic spill on fracture properties of structural steels 

      Keseler, Hanne; Westermann, Ida; Kandukuri, Sastry Yagnanna; Nøkleby, John Olav; Holmedal, Bjørn (Journal article; Peer reviewed, 2015)
      Fracture analysis of a standard construction steel platform deck, which had been exposed to a liquid nitrogen spill, showed that the brittle fracture started at a flaw in the weld as a consequence of low-temperature ...
    • Precipitation, strength and work hardening of age hardened aluminium alloys 

      Ryen, Øyvind; Holmedal, Bjørn; Marthinsen, Knut; Furu, Trond (Journal article; Peer reviewed, 2015)
      The strength and work hardening of age hardened AA6063 and AA6082 alloys have been investigated in terms of a detailed characterization of precipitate and dislocation structures obtained by TEM and SEM. Tensile and compression ...
    • Processing and indexing of electron backscatter patterns using open-source software 

      Ånes, Håkon Wiik; Hjelen, Jarle; Sørensen, Bjørn Eske; Van Helvoort, Antonius; Marthinsen, Knut (Peer reviewed; Journal article, 2020)
      A new method to increase the signal-to-noise ratio S/N of electron backscatter patterns (EBSPs) based upon principal component analysis (PCA) is presented. The PCA denoising method is applied to ten scans of EBSPs from the ...
