摘　　要： 金属磁记忆检测技术是无损检测领域的一门新兴学科,它能对铁磁金属构件的应力集中、失效、损伤等进行快速、准确的早期诊断,以防设备发生突发性的疲劳破坏。文章简述了金属磁记忆检测技术的基本原理和特点,并介绍了其在锅炉压力容器无损检测上的应用和发展。 The technique of metal magnetic memory test is a new discipline in the field of nondestructive inspection. By using this technique, the phenomenon of stress concentration and defect existed in metal magnetic material component can be diagnosed in early stage so as to protect equipment from fatigue. The fundamental principles and characteristics of metal magnetic memory technique were briefly described in this article. The development and application of this technique in non - destructive inspection for boiler and pressure vessel were also introduced.
