摘要：

Cold-rolled steels based on 0.15C - 1.5Mn-1.5Si-0.5Cu containing Cr or/and Ni were prepared, and intercritical annealing and isothermal treatment, were carried out. The addition of Cu or Cu + Ni resulted in a large increase of the retained austenite volume fraction as well as an improvement of elongation and the strength-ductility balance. However, the addition of Cr or Cu + Ni showed a dual-phase deformation behavior having higher tensile strength and lower elongation. (C) 2002 Acta Materialia Inc. Published by Elsevier Science Ltd.
