Summary
The kinetics of FeSn2 alloy growth in electrolytic tinplate have been investigated above and below the tin melting point. The experimental data below 232°C suggest a step-growth diffusional process with a period varying as function of the temperature.
Theoretical evaluation of the step-growth period was based on the solution of Pick's second law and the results obtained show reasonable agreement with the experimental findings.
The alloy step-growth process indicates penetration curves of both lattice and grain (or subgrain) boundary diffusion at about the same range of the observed dimensions of the FeSn2 crystallites.
