英文摘要	For performance evaluation of tungsten materials in fusion device, four-point bending test (4PBT) was carried out to analyze the ductile-brittle transition temperature (DBTT) of tungsten material. DBTT of industrial rolling pure tungsten measured by standard four-point bending method is under 150 degrees C, basing on analysis to the change of strain rate and strength with temperature. This result is lower than the measured values of the tensile test and impact test. Then the results of 4PBT with different loading rates and tensile test were compared to confirm the loading rate dependence of DBTTs obtained by different test methods. Finally, the reasons for the influence of test methods on DBTT measurement were analyzed and discussed.
