| Abstract: | The testing principle of the new type of electromagnetic nondestructive testing instrument based on the principle of inital magnetic permeability was described. With this new instrument the hardness of structured steel of 40Cr was tested. The result showed that the single-valued relationship between the displayed value on the instrument and hardness of the 40Cr has been acquired, therefore the problem of the "N" shape relationship between them was successfully solved. |
