摘要： PURPOSE:To enable testing of thermal fatigue under the pure water environment by providing a small autoclave about a test piece to repeatedly jet high and low temperature pure waters alternatively to the surface of a gauge section thereof. CONSTITUTION:The capacity of an autoclave 17 is minimized enough to be mounted on a test piece 18 surrounding a gauge section thereof and the heating of pure water is done with small-capacity heaters 5 and 6. Inlet nozzles for inflow of high and low temperature pure waters and output nozzles for outflow thereof are provided to uniformize the temperature distribution in the circumferential direction of the test piece while a reflux water from the autoclave 17 for high temperature pure water is introduced into a heat exchanger 7 for preheating of the low temperature pure water. Thus, a thermal fatigue testing in the pure water environment can be done efficiently in various temperature ranges.

摘要： PURPOSE:To perform an efficient testing of thermal fatigue by a method wherein a test piece and a nozzle are put together and inserted into an autoclave to ensure that high and low temperature pure waters will hit the testing surface without changing from the set temperature and flow along the surface. CONSTITUTION:A test pice 1 is mounted on chucks 2 and 3 and fixed on a load frame. A member 4 having a pure water inlet nozzle 5 and a pure water outlet nozzles 6 and 6' is provided in the perimeter of a gage section of the test piece 1. The member 4 has a sector-shaped section divided in four circumferentially. When these four sections are assembled, the internal surfaces consitutes a curved surface wth the radial distance equal from the surface of the test piece. Cylindri- cal autoclaves 8 and 8' are provided above and below the member 4. To maintain the pressure in an autoclave, a cooling cell 10 is provided behind on O ring on the internal surface of the autoclaves 8 and 8' so as to contact the chucks 2 and 3. Another cylindrical autoclave 12 is provided outside these autoclaves. The autoclave 12 is provided with a pure inlet nozzle 13 and a pure outlet nozzle 14.
