Effect of annealing upon decomposition of electrodeposited iron-zinc alloy coatings

  • C. A. Drewien

As-deposited electrodeposited iron-zinc alloy coatings containing η phase, decompose upon heating through a sequence of metastable phases. The h c p η phase transforms to b c c G, or Г-like phase via a rapid diffusional phase transformation in the vicinity of 150 °C. For bulk iron contents of 8–13 wt%, η transforms to 100% G phase. The G phase subsequently transforms at 240 °C to ς′ phase, which in turn transforms to δ or Г1 phase near 300 °C by depletion of iron from the surrounding matrix. The decomposition process may be driven by supersaturation of η with iron.
