Abstract

As a potential third-generation high-strength steel, the medium manganese steel has broad application prospects. Hot stamping technology can effectively solve the problems of large springback and large forming resistance in the cold stamping process of medium manganese steel. However, the hot stamped parts have low elongation, which cannot meet the crashworthiness requirements. The quenching-partition (QP) heat treatment process can greatly increase the elongation of the part without reducing or slightly reducing the material strength. The quenching temperature, partitioning temperature and partitioning time have a great influence on the microstructure and mechanical properties of the hot stamped part. In order to obtain the optimal process parameters, numerical simulation of the QP process based on three models were conducted. The results showed that the CCE model is simple to use but with large error. The results obtained from the carbon partition model considering interfacial migration agreed best with the experimental results.
