Prediction of processing-properties of TA15 titanium alloy based on BP neural network

Parameters of processing (temperature, strain, strain rate and cooling method) and properties (tensile strength and elongation) of TA15 titanium alloy hot-restriction-deformed were obtained through mechanical properties examination; their relationship network model was built by BP artificial neural network. The results show that the built model can reflect the relationships between processing and properties very well and has certain accuracy. It can be used for the prediction of the properties of TA15 titanium alloy under different deformation conditions. Meanwhile, the model can also serve as a guide for the heat treatment of TA15 titanium alloy.
