EFFECT OF FRICTIONAL TREATMENT OF THE AISI 321 STEEL ON THE CHANGE OF ITS HARDNESS AND MAGNETIC CHARACTERISTICS

The friction treatment of corrosion-resistant metastable steels makes it possible to improve the strength properties and operational characteristics of such materials. This is mainly due to the formation of strain-induced martensite, a stronger ferromagnetic phase, in the surface layer. Besides, modification of the phase composition changes the magnetic state of the material. The paper presents the results of the effect of varying the normal load of the indenter during surface friction treatment on the change in the phase composition and the magnetic characteristics of the AISI 321 steel. The amount of the formed ferromagnetic phase and hardness are related to the normal load of the indenter. It is shown that magnetization can be used as an informative parameter for diagnosing the formation of strain-induced martensite during the friction treatment of the AISI 321 steel.
