A model of diffusion growth of carbide-phase particles in the carburized layer of heat-resistant steels
A mathematical model of carburization of a complexly alloyed heat-resistant steel is suggested for predicting the chemical and phase composition and structure of diffusion layers that allows for formation of particles of the excess carbide phase in the carburization process. A computer-aided solution of the set of nonlinear equations makes it possible to compute the distribution of the carbon concentration, the volume fraction of the carbide phase, and the distribution of its particles over the thickness of the diffusion layer.
