By means of this particular system, it was shown that the generation of defects in the diffusion zone of metallic systems with components that differed greatly in their properties could lead to an inhomogeneous distribution of dislocations at distances that were greater than the width of the diffusion zone. A method was developed for the measurement of the effective coefficients of mutual diffusion in structurally inhomogeneous diffusion pairs. Estimates showed that, in powder diffusion pairs, mass transport in most of the diffusion zone was determined by internal stresses.
