Experimental Investigation of the Phase Relations in the Fe-Zr-Y Ternary System

Abstract

The phase relations of the Fe-Zr-Y system at 973 K and 1073 K were experimentally investigated by using the equilibrated alloys. New ternary compounds τ3-Fe3ZrY and τ4-Fe10Zr5Y2 were found in this ternary system. The solubility of Y in Fe2Zr was measured to be 3.5 at.% and the third component can hardly dissolve in the other binary intermetallic phases. Experiments have verified that Fe2.9Zr0.5Y0.5 has a solid solubility ranging from Fe73Zr12Y14 to Fe77Zr9Y13.

Phase Equilibria of the Fe–Cr–Er Ternary System in the Range 973–1273 K

“…The performance of ODS steel largely depends on the particle size and stability of the dispersed oxide nanoparticles [ 10 , 11 ]. Oxide particles containing rare earth elements, especially Y2O3, are the most widely used; however, the concentration of oxide particles containing Y is readily saturated in ODS steel [ 12 ]. To further increase the concentration of oxide particles to improve the material properties, it is necessary to add other rare earth elements.…”

New Frontiers in the Phase Structure and Functional Properties of Materials

“…This is very important for Fe–Zr–Y system applications. Within this Special Issue, isothermal sections’ information at 1073 K and 973 K of the Fe–Zr–Y system [ 2 ] are reported which can be utilized in the nuclear industry.…”
