Abstract

Based on the general provisions of the adsorption theory, J. Gibbs, in the thermo-dynamic model of solid solutions, the technique of calculation a method for the determination of the calculated adsorption activity of dissolved elements in binary solid solutions based on iron was proposed. Calculations of the grain-boundary parameter activity Аd in the ranks of the investigated elements: Si, Mn, Cr, Al, V, Ti, Mg, Mo, Nb and Ca were performed. The calculated data confirm the high surface activity well known elements such as Ca, Mg, Nb, etc.
