Estimation of hydrogen solubility in liquid alloys of iron, nickel and copper

Hydrogen solubility as a function of temperature in multi-component metallic melts was investigated. The equations for the hydrogen activity coefficients, based on the equivalent concentration principle, were proposed. These equations were obtained based on the analysis of this principle with regard to the specifics of hydrogen behaviour in the metallic alloys. The comparative calculations of hydrogen solubility in the multi-component metallic melts confirmed the applicability of the proposed equations to alloys within a wide range of composition and temperature.
