STRESSES IN THE VICINITY OF THE REACTION CELL DURING THE SYNTHESIS OF A COMPOSITE OF NONEQUILIBRIUM COMPOSITION

摘要

The process of interphase layer growth in titanium-based composite with carbon inclusions is the subject of this work. A model of the transient layer formation between the inclusion and matrix is proposed taking into account the possibility for coexistence of several phases. This problem with moving boundaries is solved analytically in quasistationary approximation. Stresses and strains forming in the reactive cell near the vicinity of the reaction-diffusion zone during the synthesis of the composite are calculated in quasistatic formulation. The effective properties of the obtained composite with particles of nonequilibrium composition are evaluated.
