Thermal deformation behavior of TB6 titanium alloy under different deformation conditions(deformation temperature of 1173-1323 K,strain rate of 0.001-1 s-1)was studied by means of Thermecmaster-Z thermal simulator.Hot compression process was stimulated by finite element simulation software,and stress and strain distribution under different deformation conditions was analyzed.The results show that stress-strain curves obtained by numerical simulation is consistent with the experimental values.Finite element software is conducted secondary development and the ODF diagram of the compressed alloy is simulated,which has a high degree of agreement with the measured ODF diagram.The distribution of equivalent stress and equivalent strain is uneven,and the maximum stress and maximum strain occur at the center of the specimen.The stress and strain increase with the decrease of deformation temperature or the increase of strain rate.After hot compression,the main texture of the alloy is R-CubeND { 001 }＜110＞texture and Cube { 001 }＜100＞texture,and it has a certain degree of heritability.Increasing the deformation temperature or strain rate can strengthen the main texture.
