Effect of Heat Treatment Process on the Mechanical Properties of 40MnBNbVTiMo Hot-Stamped Steel and Industrial Validation

This study developed a novel hot-stamped steel 40MnBNbVTiMo for automotive application, which achieves ultra-high strength by microalloying and hot stamping process optimization. The continuous cooling transformation (CCT) curve is established, revealing that Ac1, Ac3, Ms, and Mf...
