FEATURES OF MAGNETOSTRICTION IN CARBON STEELS

Magnetostriction of the tempered 60G steel in the magnetic field of a solenoid is studied. A technique is proposed for dividing magnetostriction into components, namely those induced by the displacement of interdomain boundaries and those caused by the mechanism of rotation of spin magnetic moments. The dependences of the magnetostriction components on the tempering temperature of the hardened steel are constructed. This contributes to an increase in the effectiveness (accuracy) of evaluating elastic stresses in a steel structure by magnetoelastic methods. The essence of the technique lies in the application of the Langevin function to describing the experimental magnetostriction curves of the tempered 60G steel.
