摘要：

The isothermal section of the Fe-Zn-Cr ternary system at 600 degrees C was determined using equilibrated alloys with the aid of a diffusion couple approach. The specimens were investigated by means of scanning electron microscopy equipped with energy dispersive X-ray spectroscopy, electron probe microanalysis and X-ray diffraction. The results showed that (Cr) is in equilibrium with all phases in the system except (alpha-Fe). A ternary phase with an approximate formula of Fe18Zn79Cr3 was found. The composition ranges of all intermetallic phases in the system were determined. The solubility of Zn in (Cr) is about 2.5 at.%, and that of Cr in the delta, Gamma and liquid zinc is 3.1, 5.4 and 1.4 at.%, respectively.
