摘要
介绍了金属磁记忆法-无损检测方法的原理、检测法特点、记忆信号的特征,从力学分析结果就各种因素对金属磁记忆检测结果的影响进行了讨论,并对构件隐性损伤的磁记忆检测分析、金属磁记忆检测技术的实施提出方案。
The theory of metal magnetic memory and the characteristics of the test method and memory signal are introduced in this article. From the result of the mechanics analysis, It discusses it＇s influence on the test result of metal magnetic memory and puts forward a project which is about the metal magnetic memory of the hidden damage in components and the implement of metal magnetic memory.
