Metal Magnetic Memory Method (MMM) – is a non-destructive testing method, the basic principle of which is to record and analyze the distribution of the self-leakage magnetic field generated in the stress concentration area of the parts and equipment. At this time, the self-leakage magnetic field reflects the irreversible change of the magnetization intensity in the direction of the main stress of the working load, as well as the heredity of the metal structure and manufacturing process of the parts and welds during their manufacture and cooling in the earth\'s magnetic field. In the detection, the metal magnetic memory method uses the natural magnetization intensity and the consequences of the actual deformation and metal structure changes in the metal of the parts and equipment in the form of metal magnetic memory.
