    Plastic deformation behavior was investigated in near fully dense nanostructured and ultrafine-grained bulk samples of carbon steel (0.55 wt% C) under compression and tension tests. The specimens were obtained by hot ...
  • The effect of oxide particles on the strength and ductility of bulk iron with a bimodal grain size distribution 

    Casas, C.; Tejedor Busquets, Robert; Rodríguez Baracaldo, R.; Benito Páramo, José Antonio; Cabrera Marrero, José M. (2015-03-11)
    Article
    Open Access
    The strength and ductility of bulk nanostructured and ultrafine-grained iron containing 0.39% oxygen by weight was determined by tensile tests. Samples were obtained by consolidation of milled iron powder at 500 degrees ...
