Abstract
Ultrafine grained dual phase steel with yield strength of 865. MPa and tensile strength of 1640. MPa with a high work hardening rate and uniform elongation of 7% was produced by cold rolling and intercritical annealing. The fine scale Nb-V based carbides contributed to improving the strength and work hardening. © 2013 Elsevier B.V.
