Abstract
The possibility of application of high-temperature extraction in a carrier gas to determine the content of nitrogen from titanium nitride inclusions in rail steel specimens of industrial melts and model alloys is considered. The temperatures of the onset of the dissociation of basic nitrides in rail steel are calculated under the conditions of a carbon-saturated melt. The nitrogen content in titanium nitrides in rail steel is calculated under the equilibrium conditions in the system. The experimental and calculated data on the characteristic temperatures of TiN dissociation and the nitrogen content in TiN are compared. A satisfactory convergence of the calculated and experimental data is obtained. The possibility of application of high-temperature extraction in a graphite crucible in a carrier gas flow for fractional analysis of nitrides in steel is shown.
