The results show that the stress-strain curves of TC27 titanium alloy at low temperature and high temperature roughly corresponded to the softening type and steady-state-flow type, respectively, and significant shock decline was observed when the strain rate was 70 s^-1. The dependence of temperature on flow stress at low temperature was much more significant than that at high temperature, and the dependence of strain rate decreased when the temperature was increased. Based on experimental data, two high precision constitutive equations of TC27 titanium alloy were established for temperature ranges of 700-850℃ and 850-1150℃. Observation on the microstructure shows that the amount of dynamic recrystallized grains increased with the rise of temperature or the decrease of strain rate when the temperature was higher than β transition temperature., authors=ZHANG Yeqin¹, GU Zhifei², SHA Aixue¹, HUANG Lijun¹, LU Shiqiang³, authorsList=ZHANG Yeqin, GU Zhifei, SHA Aixue, HUANG Lijun, LU Shiqiang, authorCompany=1.
