Phase diagram in the Fe corner of the Fe?Nb?Zr system at 800 °C was determined by X-ray diffraction (XRD) and quantitative microanalysis by using electron microprobe with wavelength dispersive spectrometry (SEM-WDS). The existence of two three-phase fields (C36(Zr1-xNbx)Fe2 + Fe(α) + C15) and (C36(Zr1-xNbx)Fe2 + Fe(α) + C14) and three two-phase fields (C36(Zr1-xNbx)Fe2 + Fe(α)), (Fe(α) + C14) and (Fe(α) + C15) are proposed in the present work.
