摘要：
The thermal deformation behavior and heat processability of Ti80 alloy with bimodal microstructure was investigated in temperature range of 860 similar to 1020 degrees C and strain rate range of 0.001 similar to 10 s(-1) with the maximal deformation of 50% by hot simulator, optical microscope and MATLAB software. Results show that the Ti80 alloy is negative temperature and positive strain rate sensitive material. Main softening mechanism changes from dynamic recrystallization to dynamic recovery when the temperature increases. In addition, the strain compensation constitutive equation and processing map were constructed by MATLAB programming. Correlation coefficient R between the predicted value and the experimental value of constitutive equation is 0.994, and average relative error AARE is 7.443%. The optimum processing parameter interval of Ti80 alloy is (980 similar to 1015 degrees C) in temperature and (0.013 similar to 0.100 s(-1)) in strain rate, in which the peak of power dissipation eta is 64%.
