PURPOSE: A thermal gradient fatigue testing device is provided to evaluate the thermal fatigue performance of a plurality of testing pieces at the same time, thereby reducing time required for testing. CONSTITUTION: A thermal gradient fatigue testing device(100) comprises a testing piece holder(110), a test case(120), and a plurality of cooling pipes. The testing piece holder fixes testing pieces(111). The test case includes a plurality of slits(121) where the testing piece holder is inserted and a hollow region in inside. The cooling pipes are inserted into the hollow region of the test case, thereby discharging cold air to the testing pieces. |
