This paper presents an investigation of the capabilities of artificial neural networks (ANN) in predicting some mechanical properties of Ferrite-Martensite dual-phase steels applicable for different industries like auto-making. Using ANNs instead of different destructive and non-destructive tests to determine the material properties, reduces costs and reduces the need for special testing facilities. Networks were trained with use of a back propagation (BP) error algorithm. In order to provide data for training the ANNs, mechanical properties, inter-critical annealing temperature and information about the microstructures of many specimens were examined. After the ANNs were trained, the four parameters of yield stress, ultimate tensile stress, total elongation and the work hardening exponent were simulated. Finally a comparison of the predicted and experimental values indicates that the results obtained from the given input data reveal a good ability of the well-trained ANN to predict the described mechanical properties.

An original 600MPa high aluminum galvanized dual phase steel had been successfully developed in this paper. The microstructure analysis showed that the microstructures of the steel mainly consist of ferrite and 8%~11% martensite as well as 4%~6% retained austenite which distributed around the ferrite grain boundaries. TEM analysis demonstrated that there exists lots of high density dislocation in ferrite, obvious twin-structures in martensite and some retained austenite in the microstructures. The existence of the retained austenite makes some contribution to the higher elongation of the steel. The tensile test showed that the steel delivers an excellent mechanical properties of Rp0.2=350~400MPa,Rm=610~650MPa, A80mm=26%~30%, n=0.17~0.21 and an excellent bake-hardening value of 50~70MPa. Ball-Punch Experiments showed that the galvanizing dual phase steel had a good and satisfying coating adhesion. Owe to the excellent formability, the steel has successfully been used in the production of some auto parts.
