    • FIB-SEM investigation and uniaxial compression of flexible graphite 

      Solfiti, Emanuele; Wan, Di; Celotto, Ambra; Solieri, N.; Muñoz, P.A.; Ximenes, R.F.; Heredia, J.M.; Torregrosa Martin, Martin; Perillo-Marcone, A.; Nuiry, F.X.; Alvaro, Antonio; Berto, Filippo; Calviani, M. (Peer reviewed; Journal article, 2023)
      Flexible graphite (FG) with ρ = 1 g/cm3 density is a type of highly porous and anisotropic graphite, mainly used for gaskets and sealing applications, but also suitable for energy absorption, such as in the beam dumping ...

    • Preliminary in-situ study of FIB-assisted method for aluminium solid-state welding at the microscale 

      Celotto, Ambra; Grong, Øystein; Holmestad, Randi; Sørhaug, Jørgen A; Torgersen, Jan; Vullum, Per Erik; Berto, Filippo (Peer reviewed; Journal article, 2021)
      In situ studies allow real time monitoring and deep comprehension of phenomena. This approach has been applied to the current research for the development of a novel solid-state welding technique at the microscale. The ...

    • Process Modelling Applied to Aluminium-Steel Butt Welding by Hybrid Metal Extrusion and Bonding (HYB) 

      Leoni, Francesco; Grong, Øystein; Celotto, Ambra; Fjær, Hallvard Gustav; Ferro, Paolo; Berto, Filippo (Peer reviewed; Journal article, 2022)
      In the present investigation, the numerical code WELDSIM is used to simulate butt welding of 4 mm thick plates of S355 steel and AA6082-T6 by Hybrid Metal Extrusion and Bonding (HYB). This is a new solid state joining ...
