The method shows excellent fitting precision in 980MPa and 1180MPa ultrahigh strength steel, the model has clear statistical support, and the prediction accuracy and reliability of the material hardening behavior are remarkably improved; the whole modeling process is clear in step and conventional in equipment, only a conventional two-roller cold rolling mill, a universal tensile testing machine, a wire cutting machine and general data processing software are needed to complete the modeling process, and the whole process from sample preparation to model output is high in standardization degree.
