| Abstract: | The prediction model which reflects the relation between flow stress and superplastic forming parameters of aluminum bronze was founded by the method of BP neural network, and using the model, the values of flow stress at different tensile conditions were predicted.The results show that the predicted values of the flow stress by the BP neural network are well in accordance with the test data and its errors are less than 8.5%. |
