Abstract : A lamellar microstructure observed in electrodeposited nickel-iron foil was found to consist of alternate layers of gamma phase nickel-iron alloy solid solution and of what are probably extremely thin layers of an unidentified material. The latter may be a nickel sulfide, or a fine-grained nickel-iron alloy of high sulfur content, formed with sulfur produced by reduction of the sulfonate in the addition agent. The gamma phase nickel-iron alloy consists of equiaxed grains about 0.5 micron in diameter. Alternating deposition of two phases probably accounts for the lamellar morphology. Heat treatment of the foil resulted in complete disruption of the layers and the formation of a random polycrystalline microstructure throughout. (Author)
