CANTILEVER TYPE ROTARY-BENDING FATIGUE TESTING APPARATUS UNDER HIGH TEMPERATURE ENVIRONMENT

摘要

PROBLEM TO BE SOLVED: To provide a high-temperature fatigue testing apparatus capable of performing a rotary bending fatigue test of a metal material test piece under a high temperature environment having no temperature unevenness while achieving downsizing of the apparatus.SOLUTION: The high-temperature fatigue testing apparatus and a high temperature furnace thereof comprise: a mounting member for fixing and supporting one end of a cylindrical test piece made of a metallic material by cooperating with the one end; and a load applying member for pulling the other end of the test piece downward in a vertical direction by using self weight and that measures the rotary bending fatigue strength of the test piece. The high-temperature fatigue testing apparatus includes a hollow high temperature furnace that is disposed around the axis of the test piece and controls the atmospheric temperature around the test piece. The high temperature furnace includes a heater that is disposed so as to surround the test piece and has a shape opening upward.
