Dual−phase steel with improved formability (DH steel) is developed as an evolution of conventional dual−phase steel (DP steel) to meet the increased ductility requirements associated with the fabrication of complex−shaped automotive components. Currently, DH steel with a tensile strength of 980 MPa has reached mass production, while the development of DH steel with a tensile strength of 1180 MPa has attracted significant research interest. In this study, a performance−driven machine learning methodology was employed to design the chemical composition and processing parameters of 1180 MPa−grade DH steel. Additionally, interpretable machine learning techniques were used to elucidate the fundamental relationships between the microstructural characteristics and mechanical properties. Initially, leveraging data extracted from the literature, a composition and process−performance predictive model was developed using a neural network algorithm. Subsequently, a multi−objective genetic algorithm was implemented to efficiently design the chemical composition of the novel DH steel. Following this, based on orthogonal experimental data concerning the processing parameters of the newly designed DH steel, a random forest algorithm was applied to construct predictive models for tensile strength and fracture elongation, with processing parameters serving as input variables. An optimized set of preparation process parameters was determined using a multi−objective genetic optimization algorithm. The resulting parameters are as follows: a coiling temperature of 510°C, an annealing temperature of 860°C, an annealing duration of 160 s, a slow cooling temperature of 715°C, an over−aging temperature of 340°C, and an over−aging duration of 110 s. The resulting DH steel demonstrated an exceptional balance between strength and ductility, achieving a tensile strength of 1214 MPa and an elongation after fracture (A80) of 15.5%. Finally, SHAP analysis was conducted to reveal the influence patterns of microstructural features on mechanical performance, thereby providing theoretical insights to guide the design and microstructure−performance optimization of advanced high−strength steels.

增强成形性双相钢(DH钢)是在双相钢(DP钢)基础上研发的先进高强钢,以满足汽车复杂形状零件成形对材料塑性的更高要求。目前,抗拉强度980 MPa级别的DH钢已实现规模化生产,抗拉强度1180 MPa级别的DH钢研发受到广泛关注。采用面向性能的机器学习方法,设计了一种1180 MPa级DH钢的化学成分和制备工艺参数,并通过可解释性机器学习分析了材料显微组织特征与力学性能之间的内禀关系。首先,基于文献数据,采用神经网络算法构建成分/工艺−性能预测模型,并采用多目标遗传算法高效设计了新型DH钢的化学成分。然后,基于新型DH钢的制备工艺参数正交实验结果,采用随机森林算法构建了以工艺参数为输入的抗拉强度和断后伸长率(A80)预测模型,通过多目标遗传优化算法得到了较优的制备工艺参数,即卷曲温度510℃、退火温度860℃、退火时间160 s、缓冷温度715℃、过时效温度340℃、过时效时间110 s。设计的新型DH钢具有优异的强塑性匹配,抗拉强度和断后伸长率分别为1214 MPa和15.5%。最后,采用SHAP分析揭示了组织特征对力学性能的影响规律,为先进高强钢的设计和组织性能调控提供理论参考。
