制备以含Cr或/和Ni的0.15C-1.5Mn-1.5Si-0.5Cu为基体的冷轧钢，并进行相间退火和等温处理。 Cu或Cu+Ni的添加导致残余奥氏体体积分数的大幅增加以及延伸率和强度-延展性平衡的改善。然而，Cr或Cu+Ni的添加表现出双相变形行为，具有较高的拉伸强度和较低的延伸率。 (C) 2002 Acta Materialia Inc. 由 Elsevier Science Ltd 出版。保留所有权利。
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.
