    • The Use of Aluminium in Sustainable Concrete Structures 

      Fagermo, Moa Madeleine (Master thesis, 2020)
      Denne masteroppgaven er en del av det norske forskningsprosjektet DARE2C som er finansiert av Norges forskningsråd. Ved å erstatte stålarmering med aluminiumarmering, ønsker DARE2C å utvikle en ny, mer holbar og miljøvennlig ...

    • Transient liquid phase bonding of Al-6063 to steel alloy UNS S32304 

      Saleh, Mohamed Ismail; Roven, Hans Jørgen; Khan, Tahir I.; Iveland, Terje (Journal article; Peer reviewed, 2018)
      Transient liquid phase (TLP) bonding of 6063 aluminum alloy (Al-6063) and duplex alloy 2304 stainless steel (UNS S32304) was performed using copper foil as an interlayer between the base metals. A compression load was ...

    • Utherdbare bimetall materialer fremstilt ved skrueekstrudering: AA 6060/ren magnesium 

      Mauland, Eirik (Master thesis, 2013)
      Skruekstrudering er en ny, innovativ prosess for å fremstille metaller. Prosessens store fortrinn er et relativt lav energiforbruk sammenliknet med tradisjonell ekstrudering, noe som i dagens energisamfunn er meget aktuelt. ...

    • Utmatting av AA6005 - Effekten av forskjellige tilstander 

      Tunestam, Per Fredrik (Master thesis, 2016)
      The aim of this thesis is to investigate the effect of ageing, both natural and artificial, at room temperature on the fatigue properties of AA6005. Artificial ageing was done to reach a temper state of equal hardness on ...

    • Wire and Arc Additive Manufacturing with TiC-Nanoparticle Reinforced AA5183 Alloy 

      Langelandsvik, Geir; Ragnvaldsen, Olav; Flåm, Jan Eskil; Akselsen, Odd Magne; Roven, Hans Jørgen (Peer reviewed; Journal article, 2020)
      Wire and arc additive manufacturing of aluminium-ceramic composites shows great potential to produce high strength materials. By incorporation of nanoparticles in the feedstock wire, fine-grained material with low ...

    • Wire arc additive manufacturing of AA5183 with TiC nanoparticles 

      Langelandsvik, Geir; Eriksson, Magnus; Akselsen, Odd M.; Roven, Hans Jørgen (Peer reviewed; Journal article, 2021)
      Aluminium alloys processed by wire arc additive manufacturing (WAAM) exhibit a relatively coarse microstructure with a columnar morphology. A powerful measure to refine the microstructure and to enhance mechanical properties ...

    • Wire Arc Additive Manufacturing of Aluminium Alloys 

      Langelandsvik, Geir (Doctoral theses at NTNU;2021:263, Doctoral thesis, 2021)
      Summary Additive manufacturing of metals has gained considerable attention from the industry and academia in the last decade. The attributes to create stand-alone components with novel designs and enhanced properties ...

    • Wire Arc Additive Manufacturing of an Al-Mg Aluminium Matrix Nanocompsite 

      Flåm, Jan Eskil (Master thesis, 2020)
      Målet med denne studien var å benytte 10 mm ekstrudatprofiler fra kontinuerlig skrueekstrusjon av metaller (Metal Continuous Scew Extrusion, MCSE), en ny metode for fast tilstandsproduksjons av metalltråd for additiv ...
