In this paper, Charpy notched pendulum test was used to study the impact properties of Ti6211 titanium alloy at -60 ℃, -40 ℃, -20 ℃, 23 ℃, 100 ℃, 200 ℃ and 300 ℃, respectively, and the fracture morphology was analyzed. The ductile and brittle transition temperature of the material was deduced from the area of the radiation zone. The results show that with the increase of temperature, the impact energy of the alloy increases continuously, and when the temperature reaches above 0 ℃, the impact energy increases obviously, and the area of the radiative area of the fracture surface increases gradually. Which can be inferred that the ductile and brittle transition temperature of the alloy is about 50 ℃.
