摘要：

The strain hardening behavior of nanostructured dual-phase steel fabricated by equal channel angular pressing together with subsequent intercritical annealing treatment was investigated. In contrast to conventional nanostructured steels that have negligible strain hardening capability in tension, the nanostructured dual-phase steel exhibited excellent strain hardenability due to the nanoscale grains of each constituent phase and their uniform distribution of them as well. The strain hardening behavior of such microstructure was explained by using modified Crussard-Jaoul analysis based on the Swift equation. (C) 2010 Elsevier B.V. All rights reserved.
