The Solubility of Iron in Continuous Hot-Dip Galvanizing Baths

  • Published:
Journal of Phase Equilibria

Abstract

An investigation to evaluate the effect of variations of bath temperature (450 to 480 °C) and Al concentration (0 to 0.5 %) on Fe solubility was conducted in order to better understand the formation of Fe containing intermetallic compounds in continuous galvanizing baths. Solubility relationships were first derived thermodynamically and then confirmed by experimental data. Results show that both temperature and concentration, in the range given above, significantly affect Fe solubility, and that it is important to control them within narrow limits to avoid formation of excessive amounts of intermetallic compounds. The methods used to derive the data thermodynamically and experimentally are reviewed and the results presented. Examples of practical applications are provided.
