N2 - The effects of individual substitutional element addition (Si, Al, Mn, Cu, Ni and Cr) on Hall-Petch relationship in interstitial free ferritic steels were systematically investigated by employing experimental examinations, the pie-up models and grain boundary segregation theory. Chemistry-dependent Hall-Petch coefficients were observed, which was principally interpreted based on the established correlations between the critical grain boundary shear stress and the grain boundary segregation depending on the kind of elements. Exceeded grain boundary segregation levels were found to be the predominant contributions of enhanced grain refinement strengthening abilities.
