摘要

Elevated-temperature flow behavior of Ti-6Al-3Nb-2Zr-1Mo titanium alloy was investigated by isothermal hot compression tests at strain rate from 0.001 to 1 s^-1 and in the temperature range of 820~970 °C on Gleeble-3800 simulator. The BP-ANN and regression models were established based on the experimental flow stress. Results show that the absolute value of maximum relative error obtained from the ANN model and the regression method are 4.35% and 13.9%, respectively. The average absolute relative errors are 1.42% and 6.53% corresponding to the ANN model and the regression method, respectively, which demonstrates that BP-ANN has a better prediction precision, and it can be used as the constitutive model of Ti-6Al-3Nb-2Zr-1Mo titanium alloy.
