    Abstract

    Formation of diffusion zone morphologies periodic in time and space during metal-ceramic reactions is considered as a manifestation of the Kirkendall effect. In a diffusion-controlled interaction, the Kirkendall marker plane can bifurcate, which is attributed to diverging vacancies fluxes in the reaction zone. When the Kirkendall plane is present in a phase layer, it attracts in situ-produced inclusions of "secondary-formed phase", which in turn, can result in a highly patterned microsctucture.
