【Abstract】 The new developments of TRIP high strength steels was overviewed in this paper. On the basis of summarizing the three models that are used to predict FLD, theoretical research on predicting the forming limit of TRIP steel by the proposed models and experimental determination of FLD were carried out. The differences between the predicted FLD and the experimental results indicate that all of the three models can not predict the forming limit for TRIP steels precisely. Compared with the FLD obtained by the other models, the results calculated by NADDRG model are more close to the experimental ones. In addition, the FLD of another two kinds of high strength steel, DP and ZstE180BH, are also calculated and analyzed.更多还原
