| Abstract: | Metal magnetic memory（MMM） can better detect the hidden damage of component,and this testing technology can realize early injury diagnosis.It can accurately and reliably detect the stress concentration of ferromagnetic components.Workers may take measures to prevent the accident before the component failure.By the method workers can make their losses to a minimum extent and avoid the accidenton. |
