Abstract—X-ray and neutron diffraction are indispensable in the analysis of the integral characteristics of the dispersed precipitates in high-strength medium-carbon steels. Advantages and limitations of methods application have been compared by studying changes in qualitative and quantitative compositions of dispersed phases of the wear-resistant B1700 steel after quenching and tempering in the temperature range of 150–600°C. The quantity of retained austenite decreases to zero when the tempering temperature rises above 300°C. Cementite becomes noticeable in the diffraction patterns in the same temperature range. The results of the study show that neutron instruments can more reliably detect small amounts of retained austenite, while X-ray instruments provide better resolution, especially at large scattering angles.
