    • Atomic displacements accompanying deformation twinning: shears and shuffles 

      Pond, Robert C.; Hirth, John; Serra Tort, Ana María; Bacon, D.J (Taylor & Francis Ltd., 2016-04)
      Article
      Open Access
      Deformation twins grow by the motion of disconnections along their interfaces, thereby coupling shear with migration. Atomic-scale simulations of this mechanism have advanced to the point where the trajectory of each atom ...
    • Atomic processes of shear-coupled migration in {112} twins and vicinal grain boundaries in bcc-Fe 

      Kvashin, Nikolai; García-Müller, Pablo Luis; Anento Moreno, Napoleón; Serra Tort, Ana María (American Physical Society (APS), 2020-07)
      Article
      Open Access
      Tilt {112} grain boundaries (GBs) in bcc metals perform shear-coupled grain-boundary migration by the creation and glide of disconnections. Disconnection dipoles may be created at the pristine GB at high stresses or may ...

      Anento Moreno, Napoleón; Serra Tort, Ana María; Osetsky, Yuri N. (2010)
      Article
      Restricted access - publisher's policy
      We present the results of an extensive molecular dynamics study of selfinterstitial atom (SIA) clusters containing up to 37 defects over a wide range of temperatures in iron. A long simulation time and high statistics of ...

    • Comparison of empirical interatomic potentials for iron applied to radiation damage studies 

      Becquart, C.S.; Willaime, F.; Terentyev, Dimitry; Serra Tort, Ana María; Nordlund, K.; Malerba, L.; Marinica, M.C.; Anento Moreno, Napoleón; Björkas, C.; Nguyen, H.; Domain, C.; Djurabekova, F.; Olsson, P. (2010)
      Article
      Restricted access - publisher's policy
      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 ...
    • 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
      Open Access
      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
      Open Access
      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 nickel on point defects diffusion in Fe – Ni alloys 

      Anento Moreno, Napoleón; Serra Tort, Ana María; Osetsky, Yuri (2017-06)
      Article
      Open Access
      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
      Restricted access - publisher's policy
      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} ...

      Article
      Open Access
      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
      Restricted access - publisher's policy
      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 ...
