摘要

Using the data provided in Table 6, the model thermodynamic equation for the calculation of nitrogen solubility in high-nitrogen steels of variable chemical composition, smelted in wide ranges of temperature and nitrogen partial pressure in the working gas, can be easily set. For such calculation, the equation has the following form: In order to determine the consistence of the calculated values of the activity coefficient f_N with the experimental values in quantitative terms, the whole collection of data from own studies, have been processed mathematically and represented in the lgf_(N(obl.)< = > lgf_(N(eks.). coordinate system. The distribution of measurement points relative to the ideal fitting curve of the mathematical model (17) shows good consistence between computational and experimental values within a whole, very wide range of variation of the activity coefficient f_N .
