FIELD: metallurgy.
SUBSTANCE: assayed steel samples are radiated with primary radiation of roentgen tube and there is measured intensity of secondary spectre. Also, before radiation there is additionally performed mono-chromatisation of roentgen radiation of the tube. Intensity of secondary spectre is measured by a reflected line of monochromatic roentgen radiation CuKα on lattice of iron carbides contained in assayed samples. On base of dependence obtained on standard samples there is determined content of carbon in assayed samples.
EFFECT: upgraded reliability at determination of carbon in steel.
