摘要：

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. (C) 2013 Elsevier B.V. All rights reserved.
