Iron - Nickel - Zirconium

Introduction

The system itself had not attracted much attention, and proper phase equilibria are known rather poorly. [1968Tar1, 1973Tar] studied phase equilibria in the Zr corner; unfortunately, these results seem to suffer from oxygen contamination. The review [1992Rag] contains virtually only three hypothetical sections and data for the solubility of Fe and Ni in Zr. Recently [1999Vju] has constructed a partial isothermal section at 1000°C for the Fe-ZrFe₂-Zr₂Ni₇-Ni region, combining diffusion couple technique and study of equilibrated alloys by EPMA, XRD and scanning electron microscopy.
