• Hydrogen Enhanced Fatigue Crack Growth Rates in a Ferritic Fe-3wt%Si Alloy 

      Alvaro, Antonio; Wan, Di; Olden, Vigdis; Barnoush, Afrooz (Journal article; Peer reviewed, 2018)
      It is well known that the presence of hydrogen in ferrous materials promotes both static fracture and affect the material fatigue crack growth rates. The latter is often referred to as Hydrogen Enhanced Fatigue Crack Growth ...
    • Impact of conductor assembly indentation on the fatigue properties of copper power cable wires 

      Viespoli, Luigi Mario; Johanson, Audun; Dumoulin, Stephane; Hagen, Anette Brocks; Wan, Di; Berto, Filippo; Alvaro, Antonio (Peer reviewed; Journal article, 2022)
      The production process of high voltage power cables includes the assembly of the conductor, which is composed of different layer of independent wires wound in helixes of opposite pitch for each subsequent layer. Each wire, ...
    • Room temperature creep mechanism of a Pb-Sn-Sb lead alloy 

      Viespoli, Luigi Mario; Johanson, Audun; Alvaro, Antonio; Nyhus, Bård; Berto, Filippo (Peer reviewed; Journal article, 2019)
      Lead alloys are the most common materials adopted for the production of subsea power cable sheathing. The sheathing is a layer of stable and watertight metal, which serves to prevent the electrical failure of the cable. ...
    • Subsea power cable sheathing: an investigation of lead fatigue performance 

      Viespoli, Luigi Mario; Johanson, Audun; Alvaro, Antonio; Nyhus, Bård; Berto, Filippo (Peer reviewed; Journal article, 2020)
      The protection of subsea power cables against electrical failure is achieved by the use of a watertight layer. Due to its properties of chemical stability and ductility, lead has been the material of choice for this purpose ...
    • Tensile and fatigue behavior of a Pb-Sn-Sb alloy investigated via small-scale in-situ mechanical testing in SEM 

      Wan, Di; Viespoli, Luigi Mario; Johanson, Audun; Hagen, Anette Brocks; Berto, Filippo; Alvaro, Antonio (Journal article; Peer reviewed, 2020)
      Pb-Sn-Sb alloys (E-alloy) are commonly used in subsea power cable sheathing. Due to the relatively low melting temperature, i.e. around 600 K, this type of alloy is prone to experience microstructural time-dependent evolution ...
