| Abstract: | The method of reducing load and observing by eyes were used to test the threshold of load and propagation rate of high temperature fatigue cracks in the center crack specimens which were made of alloy based Nickel. The propagation regularity and its influence factors of fatigue cracks were analyzed and discussed in high temperature. |
