  • Structure and microstructure evolution of Al-Mg-Si alloy processed by equal-channel angular pressing 

    Khelfa, T.; Rekik, M. A.; Khitouni, Mohamed; Cabrera Marrero, José M. (2017-09-01)
    Article
    Accés obert
    An ultrafine grained Al–Mg–Si alloy was prepared by severe plastic deformation using the equal-channel angular pressing (ECAP) method. Samples were ECAPed through a die with an inner angle of F = 90° and outer arc of ...
  • Estudio experimental del llenado de moldes pulvimetalúrgicos

    El objetivo principal de este trabajo es estudiar el comportamiento a fluencia de dos aceros microaleados de contenido medio de carbono, en condiciones de conformado en caliente analizando su evolución microstructural a ...
  • Constitutive model research of a TWIP steel processed by equal channel angular pressing 

    Wang, Lei; Benito Páramo, José Antonio; Calvo Muñoz, Jessica; Cabrera Marrero, José M. (2017-02)
    Article
    Accés restringit per política de l'editorial
    Influence of equal channel angular pressing (ECAP) on mechanical properties of a TWIP steel was studied, and the tensile true stress-strain curves of the steel were fitted by Ludwik, Hollomon and Swift three kinds of ...
  • Microstructure, texture and tensile properties of ultrafine/nano grained magnesium alloy processed by accumulative back extrusion 

    Fatemi Varzaneh, S. M; Zarei Hanzaki, A; Cabrera Marrero, José M. (2017-05)
    Article
    Accés obert
    An AZ31 wrought magnesium alloy was processed by employing multipass accumulative back extrusion process. The obtained microstructure, texture and room temperature tensile properties were characterized and discussed. ...

    Zhilyaev, A. P.; Samigullina, A. A.; Medvedeva, A. E.; Sergeev, S. N.; Cabrera Marrero, José M.; Nazarov, A. A. (2017-06)
    Article
    Accés obert
    Commercially pure nickel was processed by equal channel angular pressing (ECAP) through route Bc for 12 passes to obtain an ultrafine grained (UFG) microstructure and further subjected to an ultrasonic treatment (UST) ...
  • High-temperature deformation of Inconel 718Plus (TM) 

    Ozturk, Utkudeniz; Cabrera Marrero, José M.; Calvo, Jessica (2017-03-01)
    Article
    Accés restringit per política de l'editorial
    Since its introduction in 2003, alloy 718PlusTM spurred a lot of interest owing to its increased maximum service temperature over conventional Inconel 718 (704¿°C versus 650¿°C), good formability, and weldability together ...
  • Microstructural and mechanical study in the plastic zone of ARMCO iron processed by ECAP 

    Muñoz Bolaños, Jairo Alberto; Higuera Cobos, Oscar Fabián; Cabrera Marrero, José M. (2017-06-14)
    Article
    Accés obert
    Plastic deformation of ARMCO iron processed by ECAP up to a maximum equivalent strain of sixteen (i.e., 1, 4, 8, and 16 ECAP passes) following route Bc was investigated by analyzing its microstructure and the stress-strain ...
  • 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 ...
