450 °C Isothermal Section of the Zn-Fe-Cu Ternary System

Abstract

The 450°C isothermal section of the Zn-Fe-Cu ternary system was experimentally determined by Scanning Electron Microscopy (SEM) coupled with Energy Dispersive X-ray Spectrometer (EDS)/ Wave Dispersive X-ray Spectrometer (WDS), and X-ray Diffractometer (XRD). Eight three-phase regions exist in the 450°C isothermal section of the Zn-Fe-Cu ternary system. No new ternary compound was found in the system. The d Fe phase (FeZn 10 ) can be in equilibrium with all phases except the a-Fe, (Cu) and b¢ (CuZn) phase. Experimental results indicated that the solubility of Cu in the C (Fe 3 Zn 10 ) and the d Fe phase reaches as high as 17.9 and 15.2 at.%, respectively.
