在Gleeble?1500熱模擬試驗(yàn)機(jī)上通過熱壓縮試驗(yàn)研究具有初始片層組織的TC17鈦合金在變形溫度為780~860 ℃、應(yīng)變速率為0.001~10 s?1、變形量為15%~75%范圍內(nèi)的組織演變，定量分析熱變形參數(shù)對片層組織動態(tài)球化過程的影響。采用結(jié)合貝葉斯歸一化算法的BP人工神經(jīng)網(wǎng)絡(luò)，建立TC17鈦合金片層組織動態(tài)球化演變的預(yù)測模型，誤差分析表明模型精度較好。

The isothermal hot compression on Gleeble?1500 system in the temperature range of 780?860 ℃ and strain rate range of 0.001?10 s?1, was used to study the kinetics of microstructural evolution of TC17 titanium alloy with initial lamellar microstructure. The quantitative results show that dynamic globularization kinetics and kinetics rate are sensitive to deformation conditions. A model for predicting volume fraction of dynamic globularization was built based on the above quantitative results and BP artificial neural network (ANN) combined with Bayesian regularization. The well coincidence of the predicted results with measured ones shows the feasibility of the model.
