摘要
介绍一种表面裂纹高温断裂韧性Ｋ１ｅ的测试方法，该技术对试样自动加温控温，自动绘制力ｐ与裂纹咀张开位移Ｖ（ｐ—Ｖ）曲线。测试精度高。
In this paper,a technique of testing the hot fracture toughness KIe of surface cracks is recommended. With the help of the technique,the test sample is heated,the temperature is controlled and the (p-V) curve of the force p versus the open displacement V of a crack mouth is drawn automatically. The test accuracy is very high.
