Grain refinement and mechanical properties of Fe-30Mn-0.11C steel
Abstract
In this work, fully recrystallized ultrafine-grained (UFG) Fe-30Mn-0.11C steel with mean grain size of 1 μm was successfully produced by using traditional cold rolling and annealing process. The UFG Fe-30Mn-0.11C steel exhibited high tensile ductility (∼60.4%) and yield strength (381 MPa). Grain refinement and source hardening were responsible for achieving this combination of strength and ductility in the studied material.
