DOI: 10.1016/j.scriptamat.2018.04.028
Abstract: Abstract The ultrafine grain with the effective grain size of 1.10 μm was fabricated by intercritical deformation on low-carbon microalloyed steel, which was finer than the deformation induced ferrite transformation (DIFT) at 1.55 μm. During intercritical deformation,… read more here.
