-
摘要: 首先介绍了内应力产生的原因,然后分别介绍了内应力的无损检测方法(X射线衍射法、中子衍射法、磁测法和超声波检测法)及有损检测法(盲孔法)的基本原理、优缺点和研究现状,最后对内应力检测方法的应用前景进行了展望。Abstract: This paper first introduced the causes of internal stress, then introduced the basic principles, advantages and disadvantages, and research status of nondestructive testing methods (X-ray diffraction method, neutron diffraction method, magnetic measurement method and ultrasonic detection method) and destructive testing method (blind hole method), respectively. Finally, the application prospect of internal stress testing method was prospected.
