| Abstract: | The physical essence of the nondestructive quality control of mediate-and high-temperature tempering of parts made of carbon and low-alloyed steels containing more than 0.3% carbon, which is performed on the basis of measurements of the secondary residual magnetic inductance (magnetization) and relaxation coercive force of a body, is considered. Examples of the inspection of the hardness of tempered parts made of a number of steels of different grades are reported. |
