本文研究了形变温度及形变量对亚温形变淬火双相15钢的显微组织和力学性能的影响,探讨了发展纤维组织双相钢的可能性。试验结果表明,亚温形变淬火双相15钢的强度主要受钢中铁素体相的强化状态所控制,并取决于马氏体的体积分量和形变强化效果的综合作用。对15钢在800℃左右进行80%形变后淬火,可以获得纤维组织发达的双相钢,具有良好的强塑性匹配。 In this paper, the effect of deformation temperature and deformation on the microstructure and mechanical properties of dual-phase 15 steels quenched and tempered by sub-temperature was investigated. The possibility of developing dual-phase steels with fiber structure was discussed. The experimental results show that the strength of the sub-tempered dual-phase 15 steel quenched by quenching is mainly controlled by the strengthening state of the ferrite phase in the steel and depends on the combined effect of the volume fraction of martensite and the strengthening effect of deformation. The 15 steel at about 800 ℃ after 80% deformation after quenching, we can get developed dual-phase steel fiber organization, has a good strong plastic matching.
