  • Consolidation of AA7075-2wt%ZrO2 composite powders by severe plastic deformation via ECAP 

    Hernadez-Martinez, S. E.; Cruz-Rivera, J. J.; Martinez-Sanchez, R.; Garay Reyes, C. G.; Muñoz Bolaños, Jairo Alberto; Cabrera Marrero, José M.; Hernandez Rivera, J. L. (2016-10)
    Article
    Open Access
    The powders of the AA 7075-ZrO2 were mixed by mechanical milling, but it was found that the system presents a few disadvantages when processed by conventional sintering and hot extrusion, since intermetallic phases between ...
  • High cycle fatigue of ARMCO iron severely deformed by ECAP 

    Muñoz Bolaños, Jairo Alberto; Higuera Cobos, Oscar Fabián; Cabrera Marrero, José M. (2017-01-10)
    Article
    Open Access
    The high-cycle fatigue behavior of ARMCO iron severely deformed by Equal Channel Angular Pressing (ECAP) at room temperature through route Bc until 8 passes, with an average grain size of ~365 nm, was studied and compared ...
  • 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
    Open Access
    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 ...
  • Propiedades mecánicas y microestructurales del hierro Armco sometido a severa deformación plàstica mediante presión en canal angular de sección constante (ECAP) 

    Muñoz Bolaños, Jairo Alberto (Universitat Politècnica de Catalunya, 2016-07-21)
    Doctoral thesis
    Open Access
    Ultrafine grain size Armco iron has been obtained through severe plastic deformation through equal channel angular pressing (ECAP) at room temperature, using a die with interna! angle et> = 90 º, and an angle 4J = 37 º ...
  • Strain hardening behavior of ARMCO iron processed by ECAP 

    Cabrera Marrero, José M.; Muñoz Bolaños, Jairo Alberto; Higuera Cobos, Oscar Fabián (Institute of Physics (IOP), 2014-07)
    Article
    Open Access
    The strain hardening behavior of an ARMCO iron processed by ECAP at room temperature up to sixteen passes following route Bc was investigated through Hollomon and differential Crussard-Jaoul models. Results indicate that ...
