La. Giannuzzi et al., HIGH-RESOLUTION ELECTRON-MICROSCOPY OF THE IRON-ZINC DELTA INTERMETALLIC PHASE - FINAL REPORT - AESF SUMMER 1992 RESEARCH GRANT, Plating and surface finishing, 80(2), 1993, pp. 54-56
The Fe-Zn system has widespread technological applications because of
the frequent use of zinc as a surface finish for iron. The role of the
zinc is to inhibit corrosion of the iron by cathodic protection. Four
low temperature intermediate phases can form in binary Fe-Zn alloys a
nd are found in the zinc-rich portion of the phase diagram.1 The forma
tion of intermediate phases in a binary alloy system can be deleteriou
s because of the typically brittle nature of these phases and the resu
lting impact they have on the mechanical stability of the system.
