Pure Fe specimens were annealed in pure Zn and binary Pb-Zn melts at temperatures between 733 and 818K for various times. The kinetics of the reaction diffusion between the specimen and the melt was examined. In the case of the pure Zn melt, the Γ, Γ1, compact δ1 and palisade δ1 phases were formed between the Fe specimen and the melt at temperatures higher than 778K, and the ζ phase as well as these four intermetallic phases was observed at temperatures lower than 768K. In the case of the binary Pb-Zn melt, however, the formation of the intermetallic phases with high zinc concentrations was inhibited with decreasing zinc content of the melt. At temperatures between 778 and 808K, fragmentation of the palisade δ1 phase occurred during the annealing in the Pb-Zn melt with zinc content higher than 40 mass%.
