  • Equal channel angular pressing of a TWIP steel: microstructure and mechanical response 

    Wang, Lixin; Benito Páramo, José Antonio; Calvo Muñoz, Jessica; Cabrera Marrero, José M. (Springer, 2017-06-01)
    Article
    Accés obert
    A Fe–20.1Mn–1.23Si–1.72Al–0.5C TWIP steel with ultrafine grain structure was successfully processed through equal channel angular pressing (ECAP) at warm temperature up to four passes following the BC route. The microstructure ...
  • Twin-induced plasticity of an ECAP-processed TWIP steel 

    Wang, Liang; Benito Páramo, José Antonio; Calvo Muñoz, Jessica; Cabrera Marrero, José M. (2017-02-01)
    Article
    Accés obert
    The TWIP steels show high strain hardening rates with high ductility which results in high ultimate tensile strength. This makes their processing by equal channel angular pressing very difficult. Up to now, this has only ...
  • Activation process of air stable nanoscale zero-valent iron particles 

    Ribas Fargas, David; Cernik, M.; Benito Páramo, José Antonio; Filip, J.; Martí Gregorio, Vicenç (2017-07-15)
    Article
    Accés obert
    Nanoscale Zero Valent Iron (nZVI) represents a promising material for subsurface water remediation technology. However, dry, bare nZVI particles are highly reactive, being pyrophoric when they are in contact with air. The ...
