Formation of Two-Phase Zones During Internal Oxidation of Binary Alloys

This research studies the formation patterns of two-phase regions during the internal oxidation process in weak-alloyed binary alloys. The goal of the research is the creation of a mathematical model for the internal oxidation process, which describes the kinetics of the formation and evolution of internal oxidation zones. A theoretical analysis of the two-phase diffusion saturation process with light components applied to binary alloys is given. The simulation and experimental results demonstrate that the distribution of structural parameters in the two-phase area has a complex, non-monotonous nature. The results of the provided research could be used for developing new technologies in thermal and chemical-thermal treatments for dispersed strengthening of materials using internal oxidation.
