中文摘要：利用不同设备研究热处理工艺对双相钢组织和性能的影响。结果表明：亚温区二次淬火可使双相钢获得更高的强度和更好的塑性，而且，随亚温淬火温度升高，双相钢的强度提高，塑性改善。
英文摘要：The effects of heat treatment process on the microstructure and properties of dual-phase steel were studied using advanced technical equipment. The results show that the higher strength and better plasticity can be obtained through intermediate quenching in two-phase region. The strength and plasticity of dual-phase steel is improved with the increase of quenching temperature.
