通过HSLA钢中各组成相的体积分数、铁素体晶粒尺寸、析出相的尺寸和体积分数等参数，分别考虑了细晶强化、相变强化和析出强化等强韧化机制对强度和韧性等机械性能的影响，建立了HSLA钢组织一性能对应关系的预测模型。模型的预测精度通过两种HSLA钢实验室控轧控冷的组织一性能实验数据获得验证。
According to the volume fraction, the ferrite grain size, the size and the volume fraction of the precipitated phase in the HSLA steel, the effects of strengthening and toughening mechanisms such as grain strengthening, phase transformation strengthening and precipitation strengthening on the strength and toughness And other mechanical properties of the HSLA steel to establish a corresponding relationship between performance prediction model. The prediction accuracy of the model was verified by the experimental data of the microstructure-property test of two HSLA steels.
