The paper presents a procedure for carrying out quantitative structural-phase analysis (CSFA) based on the results of X-ray diffraction studies and measurement of specific volumes. The CSFA procedure was applied to constructing the phase composition diagrams illustrating structural changes in steels due to the exposure to an external magnetic field during quenching. The changes in the phase composition and distribution of carbon, caused by the magnetic field effect, result in an increased degree of martensite decomposition according to a two-phase mechanism, occurrence of fine carbon delamination, and formation of highly dispersed carbide phase particles, leading to the creation of a structural state, characteristic of steel after an ordinary quenching and low-temperature tempering.
