Physicochemical characteristics of the internal nitriding of multicomponent alloys

Abstract

Internal nitriding is the saturation of the deep layers of an alloy with nitrogen, which produces a structure composed of disperse nitride particles distributed in a solid solution. This distinguishes internal nitriding from conventional nitriding where a continuous nitride zone is formed in the surface layer. Therefore, internal nitrogenization, as in other processes of alloy saturation with implantation elements (e.g., internal oxidation), ensures the disperse strengthening of the alloy. The degree of strengthening is dependent on the amount and dispersion of the evolved nitrides and is associated with their thermodynamic stability and coagulation resistance. The study of the characteristics of internal nitriding of multicomponent alloys is of interest.
