    摘要:

    將經(jīng)過熱約束變形的TA15鈦合金進(jìn)行力學(xué)性能測(cè)試，獲得了工藝（溫度、應(yīng)變、應(yīng)變速率及冷卻方式）、性能（抗拉強(qiáng)度、延伸率）參數(shù)數(shù)據(jù)，利用BP人工神經(jīng)網(wǎng)絡(luò)建立起其間的關(guān)系網(wǎng)絡(luò)模型。研究表明：所建立的網(wǎng)絡(luò)可以很好地反映出本材料的工藝-性能之間的關(guān)系并且具有一定的精度，網(wǎng)絡(luò)模型可以用來預(yù)測(cè)不同變形條件下TA15鈦合金的性能。

    Abstract:

    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.
