| Magnetic measurements are becoming an important group of nondestructive testing methods for metallurgical products. In the present paper we focus on the possibility to avail of the so-called law of approach to magnetic saturation for determination of variations of mechanical properties (residual stress) in drawn wires. The measured M=f(H) dependences are reasonably well fitted with the simplest Weiss relationship. The value of model parameter a depends significantly on processing conditions. |
