      Accés restringit per política de l'editorial
      The performance of four recent semi-empirical interatomic potentials for iron, developed or used within the FP6 Perfect Project, is evaluated by comparing them between themselves and with available experimental or, more ...
    • Disconnection-mediated motion of ⟨110⟩ tilt grain boundaries in a-Fe 

      Kvashin, Nikolai; Anento Moreno, Napoleón; Serra Tort, Ana María (American Physical Society (APS), 2022-05)
      Article
      Accés obert
      It is possible for ⟨110⟩ tilt grain boundaries (GBs) in bcc metals to perform a conservative displacement by the glide of intrinsic GB line defects, namely, disconnections. The paper presents the characteristic of these ...
    • Dislocation structure and mobility in hcp rare-gas solids: quantum versus classical 

      Sempere Llagostera, Santiago; Serra Tort, Ana María; Boronat Medico, Jordi; Cazorla Silva, Claudio (Multidisciplinary Digital Publishing Institute (MDPI), 2018-02-01)
      Article
      Accés obert
      We study the structural and mobility properties of edge dislocations in rare-gas crystals with the hexagonal close-packed (hcp) structure by using classical simulation techniques. Our results are discussed in the light of ...
    • Edge dislocations as sinks for sub-nanometric radiation induced defects in a-iron 

      Anento Moreno, Napoleón; Malerba, L.; Serra Tort, Ana María (Elsevier, 2018-01)
      Article
      Accés obert
      The role of edge dislocations as sinks for small radiation induced defects in bcc-Fe is investigated by means of atomistic computer simulation. In this work we investigate by Molecular Statics (T = 0K) the interaction ...
    • Effect of irradiation defects on the plastic slip of {112} grain boundary: atomic scale study 

      Kvashin, Nikolai; Terentyev, Dimitry; Serra Tort, Ana María; Anento Moreno, Napoleón (2022-11)
      Article
      Accés restringit per política de l'editorial
      S3{112} grain boundary (GB) is known to exhibit plastic slip in bcc metals, which overall contributes to the good ductility and toughness of such metals as iron, matrix element for the steels applied in nuclear industry. ...
    • Effect of nickel on point defects diffusion in Fe – Ni alloys 

      Anento Moreno, Napoleón; Serra Tort, Ana María; Osetsky, Yuri (2017-06)
      Article
      Accés obert
      Iron-Nickel alloys are perspective alloys as nuclear energy structural materials because of their good radiation damage tolerance and mechanical properties. Understanding of experimentally observed features such as the ...
    • Evolution of matrix-twin interfaces of (101¯2) twin in magnesium 

      Ostapovets, Andriy; Serra Tort, Ana María (2015-10-01)
      Article
      Accés restringit per política de l'editorial
      Recently, the presence of basal-prismatic interfaces in hexagonal close packed metals became subject of intensive investigation. We model the {101¯2} twin in magnesium bounded by two types of boundaries, i.e. {101¯2} ...

    • Grain boundary mediated plasticity: the role of grain boundary atomic structure and thermal activation 

      Terentyev, Dimitry; Bakaev, A.; Serra Tort, Ana María; Pavia, F.; Baker, K. L.; Anento Moreno, Napoleón (2018-03)
      Article
      Accés obert
      The interaction of dislocation pile-ups with several tilt grain boundaries (GB) is studied in copper by using a hybrid continuum-atomistic approach. The effects of temperature, pile-up intensity and GB structure on absorption ...

      Article
      Accés obert
      Mobile grain boundaries (GB) may have specific interactions with radiation-induced defects compared with static GBs. In this paper, we consider the GB-defect interactions for the {1 1 2} GB that performs shear coupled grain ...
