【Abstract】 Analyzing the relationship between mechanical properties and influence factors, the paper points out that the mechanical properties of ductile cast iron depends on microstructure and chemical composition in certain production process. An optimal model of mechanical properties in ductile cast iron is set up based on Matlab neural network toolbox and BP model. The processing, namely the structure design, the data processing, the network initialization, the network training and simulation about the model, is introduced. The method plays an important role in improving the mechanical properties in ductile cast iron.更多还原
