摘　　要：将经过热约束变形的TA15钛合金进行力学性能测试,获得了工艺(温度、应变、应变速率及冷却方式)、性能(抗拉强度、延伸率)参数数据,利用BP人工神经网络建立起其间的关系网络模型。研究表明:所建立的网络可以很好地反映出本材料的工艺-性能之间的关系并且具有一定的精度,网络模型可以用来预测不同变形条件下TA15钛合金的性能。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
