Resumen *

The Fe-rich corner of the Fe-Nb-Zr phase diagram was studied at 1200 ◦C by using synchrotron X-ray diffraction and quantitative electron probe microanalysis. The Fe2Nb(C14) hexagonal Laves phase, Fe23Zr6 and Fe(α) compounds were found. The existence of two three-phase fields (Fe2(Zr1-xNbx)(C14) +Fe(α) +Fe23Zr6) and (Fe2(Zr1-xNbx)(C14) +Fe2Zr(C15) +Fe23Zr6) and five two-phase fields (Fe2(Zr1-xNbx)C14 +Fe(α)), (Fe(α) +Fe23Zr6), (Fe23Zr6 +Fe2Zr(C15)), (Fe2(Zr1-xNbx)(C14) + Fe23Zr6) and (Fe2(Zr1-xNbx)(C14) +Fe2Zr(C15)) are proposed in the present work. The phase diagram section at 1200 ◦C in the Fe-rich corner of the Fe-Nb-Zr system has been re-drawn. Información suministrada por el agente en SIGEVA
