Abstract

Ultrafine grained dual phase steel consisting of ferrite and martensite of ∼1 μm was processed by equal channel angular pressing and subsequent intercritical annealing. This steel exhibited the superior combination of higher strength, larger elongation and more rapid strain hardening compared to those of coarse grained dual phase steel.
