Growth kinetics of second phase, which appearing between first phase and second component after first component exhausting, is analysed. As shown, a diffusion homogenization of the first phase leads to near linear second phase growth laws in planar and cylindrical samples. As founded, the second phase velocity is higher in cylindrical samples then in planar samples because of internal stress relaxation arising due to first phase growing with negative dilatation. Method to estimate a time of exhausting one of the components is proposed too.
Key words: diffusion, reaction, phase-growth law, intermetallics, grain boundaries.
