Abstract
The magnetic properties of samples prepared from two-phase austenitic–ferritic and austenitic–martensitic chromium–nickel steels of various grades are investigated. The aim of the research was to establish a correlation between the magnetic parameters of the studied steels in fields of 250–600 A/cm and the percentage of the ferromagnetic phases of ferrite and deformation martensite. To this end, we determined the parameters of the magnetic hysteresis loops of the samples (coercive force, maximum magnetization, remanent magnetization) and the parameters of the field dependences of differential magnetic susceptibility (maximum differential magnetic susceptibility, area under dependences). It is shown that based on the value of maximum differential magnetic susceptibility, one can unambiguously determine the content of ferrite or deformation martensite in the studied steels, regardless of the magnetizing field amplitude.
