    • Physical mechanisms and parameters for models of microstructure evolution under irradiation in Fe alloys. Part I: pure Fe 

      Malerba, L.; Anento Moreno, Napoleón; Balbuena, Juan Pablo; Becquart, C.S.; Castin, Nicolas; Caturla, Maria José; Domain, C.; Guerrero, C.; Ortiz, Christophe; Pannier, B.; Serra Tort, Ana María (Elsevier, 2021-12)
      Article
      Accés obert
      This paper is the first of three that overview the main mechanisms that drive the microstructure evolution in Fe alloys under irradiation. It focuses on pure a-Fe and compiles the parameters that describe quantitatively ...

    • Review of non-classical features of deformation twinning in hcp metals and their description by disconnection mechanisms 

      Ostapovets, Andriy; Serra Tort, Ana María (Multidisciplinary Digital Publishing Institute (MDPI), 2020-09)
      Article
      Accés obert
      The study of deformation twinning has long history. However new, sometimes surprising, findings have shown that the phenomenon of deformation twinning still is not completely understood. The study of deformation twinning ...

    • Simulació a escala atòmica de defectes en metalls i aliatges 

      Serra Tort, Ana María (Universitat Politècnica de Catalunya. Escola Tècnica Superior d'Enginyers de Camins Canals i Ports de Barcelona, 2011-11-16)
      Comunicació de congrés
      Accés obert
      Les propietats físiques dels materials amb estructura atòmica ordenada estan directament relacionades amb la estructura cristal·lina dels àtoms que els formen i, per tant, es veuen fortament modificades pels defectes ...

    • Slip dislocation and twin nucleation mechanisms in hcp metals 

      Ostapovets, Andriy; Serra Tort, Ana María (Springer, 2017-01)
      Article
      Accés obert
      A new nucleation mechanism is proposed for {101¯1} deformation twin in hcp materials. The mechanism is based on the results of atomistic computer simulations. It was found that under high shear stress applied on {101¯1} ...

    • Structure and strength of (1 1 0) tilt grain boundaries in bcc Fe: an atomistic study 

      Terentyev, Dimitry; He, X.; Serra Tort, Ana María; Kuriplach, J. (2010-08)
      Article
      Accés restringit per política de l'editorial
      In this work we study a set of $\left<{1\:1\:0}\right>$ tilt grain boundaries (GB) with a misorientation angle varied from 26º to 141º by applying atomistic calculations in α-Fe. A set of different interatomic potentials ...

    • The role of nickel in radiation damage of ferritic alloys 

      Osetsky, Yuri; Anento Moreno, Napoleón; Serra Tort, Ana María; Terentyev, Dimitry (2015-02-01)
      Article
      Accés obert
      According to modern theory, damage evolution under neutron irradiation depends on the fraction of self-interstitial atoms (SIAs) produced in the form of one-dimensional glissile clusters. These clusters, having a low ...

    • Unravelling the nucleation and growth of {11-22} twins 

      Ostapovets, Andriy; Verma, Ritu; Serra Tort, Ana María (2022-07)
      Article
      Accés obert
      A recently proposed mechanism of {11-22} twin nucleation in Ti by reverse phase transformation is analysed. It is demonstrated that, not only nucleation, but also growth mechanism of an already formed twin is connected to ...
