  • Atomistic simulations of tensile deformation of a nanoporous high-entropy alloy 

    Deluigi, O. R.; Valencia, F.; Amigo, N.; Aquistapace, F.; Gonzalez, R. I.; Bringa, E. M. (2022)
    High-entropy alloys (HEAs) display outstanding mechanical properties which make possible new technological applications. There are many studies of bulk HEAs, but here we focus on FeCrNiCuCo single-crystal face-centered ...

  • Influence of grain size on mechanical properties of a refractory high entropy alloy under uniaxial tension 

    Deluigi, O. R.; Valencia, F.; Tramontina, Diego Ramiro; Amigo, N.; Rojas-Nunez, Javier; Bringa, E. M. (2023)
    There is a growing interest in High Entropy Alloys (HEAs) due to their outstanding mechanical properties. Most simulation studies have focused on face-centered cubic (fcc) HEAs; however, bcc HEAs can offer a larger elastic ...

  • Molecular dynamics simulation of surface phenomena due to high electronic excitation ion irradiation in amorphous silica 

    Prada, Alejandro; Sánchez-Pérez, Francisco; Bailly-Grandvaux, Mathieu; Bringa, Eduardo; Caturla, María José; Perlado, José M.; Kohanoff, Jorge; Peña-Rodríguez, Ovidio; Rivera, Antonio (2023)
    We studied by means of an atomistic model based on molecular dynamics the thermal evolution of surface atoms in amorphous silica under high electronic excitation produced by irradiation with swift heavy ions. The model was ...

  • Nanoindentation of CuZr metallic glasses subjected to thermal–pressure treatments 

    Amigo, Nicolás; Aquistapace, F.; Sayad, Saeid; Valencia, F.; Alahyarizadeh, Ghasem; Bringa, E. M. (2024)
    In this work, nanoindentation tests were performed on CuZr MGs subjected to thermal–pressure treatments using molecular dynamics simulations, with pressures in the range of 0 to 20 GPa. No significant variations in the ...

  • Nanoporous amorphous carbon with exceptional ultra-high strength 

    Castillo-Castro, Daniel; Correa, Felipe; Aparicio, Emiliano; Amigo, Nicolás; Prada, Alejandro; Figueroa, Juan; González, Rafael I.; Bringa, Eduardo; Valencia, F. (2023)
    Nanoporous materials show a promising combination of mechanical properties in terms of their relative density; while there are numerous studies based on metallic nanoporous materials, here we focus on amorphous carbon with ...

  • Plastic behavior of a nanoporous high-entropy alloy under compression 

    Deluigi, O. R.; Amigo, N.; Valencia, F.; Aquistapace, F.; Tramontina, Diego Ramiro; Gonzalez, R. I.; Bringa, E. M. (2023)
    Nanoporous High-entropy alloys (HEA) have attracted increasing attention in recent years due to their remarkable mechanical properties and their capability as storage devices. However, chemical complexity involves fluctuations ...
