    • Structural evolution of metallic glasses during annealing through in-situ Synchrotron X-ray diffract 

      Pineda Soler, Eloi; Boneu, Francesc; Bruna Escuer, Pere; Pradell Cara, Trinitat; Labrador, Ana; Crespo Artiaga, Daniel (2008-05)
      Article
      Accés obert
      In this work we study the structural evolution of Al and Fe based metallic glass compositions. The samples were obtained as ribbons by melt-spinning, their glass stability and crystallization were analyzed by calorimetry ...

    • Structural study of conventional and bulk metallic glasses during annealing 

      Pineda Soler, Eloi; Hidalgo, I.; Bruna Escuer, Pere; Pradell Cara, Trinitat; Labrador, Ana; Crespo Artiaga, Daniel (2007)
      Article
      Accés obert
      Metallic glasses with conventional glass-forming ability (Al-Fe-Nd, Fe-Zr-B, Fe-B-Nb compositions) and bulk metallic glasses (Ca-Mg-Cu compositions) were studied by synchrotron X-ray diffraction during annealing throughout ...

    • Structure and Mössbauer analysis of melt-spun Fe-Pd ribbons containing Ni and Co 

      Rekik, Hanen; Chemingi, Mahmoud; Bachaga, Tarek; Cherif, Amal; Bruna Escuer, Pere; Suñol Martinez, Juan Jose; Khitouni, Mohamed (2015-06-05)
      Article
      Accés obert
      Fe68.45Pd28.21Co1.66Ni1.66 alloy in ribbon geometry was produced by melt spinning. The microstructure of the samples was examined using scanning electron microscopy. The structural identification of the as-spun ribbon ...

    • Structure, mechanical properties and nanocrystallization of (FeCoCrNi)-(B,Si) high-entropy metallic glasses 

      Panahi, Seyedeh Leila; Fornell, Jordina; Popescu, Catalin; Pineda Soler, Eloi; Sort Viñas, Jordi; Bruna Escuer, Pere (2022-02)
      Article
      Accés obert
      New high-entropy metallic glasses were produced by adding B and Si to the Fe25Co25Cr25Ni25 high entropy alloy. Extremely hard materials were obtained by inducing structural relaxation and nanocrystallization in the ...

    • Study of crystallization process of Fe65Nb10B25 and Fe70Nb10B20 glassy metals 

      Torrens i Serra, Joan; Bruna Escuer, Pere; Rodríguez Viejo, Javier; Pradell Cara, Trinitat; Clavaguera Mora, Maria Teresa (2007)
      Article
      Accés obert
      The devitrification of the Fe65Nb10B25 and Fe70Nb10B20 metallic glasses produced by melt spinning has been studied by calorimetry (DSC), X-ray diffraction (XRD) and transmission Mössbauer spectroscopy (TMS). Calorimetric ...

    • The magnetopyroelectric effect: heat-mediated magnetoelectricity in magnetic nanoparticle-ferroelectric polymer composites 

      Llacer Wintle, Joaquin; Renz, Jan; Hertle, Lukas; Veciana, Andrea; von Arx, Denis; Wu, Jiang; Bruna Escuer, Pere; Vukomanovic, Marija; Puigmartí Luis, Josep; Nelson, Bradley J.; Chen, Xiang Zhong; Pané Vidal, Salvador (Royal Society of Chemistry (RSC), 2023-01-01)
      Article
      Accés obert
      Magnetoelectricity enables a solid-state material to generate electricity under magnetic fields. Most magnetoelectric composites are developed through a strain-mediated route by coupling piezoelectric and magnetostrictive ...

    • Thermal and structural study of nanocrystalline Fe(Co)NiZrB alloys prepared by mechanical alloying 

      Gonzalez, A; Escoda, L; Suñol Martinez, Juan Jose; Shao, G.; Arcondo, B.; Bruna Escuer, Pere (2010-01)
      Article
      Accés restringit per política de l'editorial
      Three nanocrystalline alloys, Fe75-xCox(Ni70 Zr30)15B10 (x = 0, 10, and 20), were synthesized from elemental powders in a planetary high-energy ball mill. Their microstructure, magnetic properties, and thermal stability were ...
