Abstract
Thermodynamic data about the TiN and VN formation in iron melts were obtained at the National University of Science and Technology “MISIS” using advanced Sieverts apparatus based on the compensation method of gas volume and pressure measuring using high-sensitive zero reader (pressure sensor). Using of such method for gas – metal interaction investigations was early offered and realized at Chelyabinsk Institute of Metallurgy by Professor A.G. Ponomarenko. Obtained experimental data were used for the calculations of Ti and V initial activity coefficients in the iron-based solutions. Thus the refined Gibbs energy values of VN formation from elements were used. Obtained values for the Ti and V initial activity coefficients in the ironbased solutions: = 0.055 and = 0.24 are compatible with the literature data.
