Abstract
The formation of a submicron fibrous (SMF) structure in low carbon low alloy steels under severe warm rolling is investigated. It is shown t hat by varying modes of deformation one can obtain structures with eit her equilibrium or nonequilibrium grain boundaries (GBs). It is establ ished that SMF structure provides for a sharp increase in strength pro perties (by a factor of 23) as compared to those of coarse-grained mat erial. An analysis of this effect based on Hall-Patch relation models is given.
