Early Stages of Plastic Deformation in Low and High SFE Pure Metals

open access: yesMetals, 2020
Severe plastic deformation (SPD) techniques are known to promote exceptional mechanical properties due to their ability to induce significant grain and cell size refinement. Cell and grain refinement are driven by continuous newly introduced dislocations
