• Stability of ultra-fine and nano-grains after severe plastic deformation: a critical review

    1 month ago - By Springer

    Abstract
    In this critical note, the thermal stability behavior of ultra-fine grained and nano-structured metals and alloys produced through severe plastic deformation techniques is reviewed. For this case, the common engineering metals with body-centered cubic , face-centered cubic , and hexagonal close-packed crystal structures such as aluminum, copper, nickel, magnesium, steel, titanium, and their relating alloys were assessed. Microstructural evolution in these severely deformed materials following post-processing annealing treatment was investigated for various times and temperatures...
