“…But the as gap-type compounds Sm 3 (Fe,Ti) 29 N y and Sm 3 (Fe,Ti) 29 C y exist the problem of thermal decomposition. In previous work, we have determined the phase relations of the Y-Fe-Cr ternary system at 773K [9], and the compounds Y 3 Fe 29-x Cr x were observed in as-cast alloy samples. Here, we reports the results of the investigation on the thermal stability of the compounds Y 3 Fe 29-x Cr x by experiments.…”

Binary compound Y3Fe29cannot be directly formed by rare earth Y and Fe and the third element M (non-iron transition elements) must be introduced to form ternary compound Y3(Fe,M)29. In this work, six alloys with compositions of the Y3Fe29-xCrx(x=1,2,3,4,5,6) were prepared and investigated by X-ray diffraction (XRD), Scanning electron microscopy (SEM) and differential thermal analysis (DTA). The study on the thermal stability of these compounds points to that the compoundY3(Fe,Cr)29is a high temperature phase and exists above 1100K. The alloys with single-phase of Y3(Fe,Cr)29was decomposed into Y2(Fe,Cr)17and Y(Fe,Cr)12annealed at high temperature 1100K.

The study of this ternary system by [1959Far] was reviewed by [1992Rag], who presented two tentative isothermal sections at $1240 and 600°C. Recently, [2010He] reinvestigated this system at 500°C and confirmed the presence of a previously-reported ternary compound (Fe,Cr) 12 Y. Binary SystemsIn the Fe-Cr phase diagram, a gamma loop restricts the fcc region to about 12 at.% Cr. The bcc a phase is stable over a large region. Ternary Isothermal SectionWith starting metals of 99.9% Cr, 99.99% Fe and 99.9% Y, [2010He] arc-melted under Ar atm 188 alloys. The alloys were given a final anneal at 500°C for 10 days and quenched in liquid nitrogen. The phase equilibria were studied with x-ray powder diffraction, differential thermal analysis, and scanning electron microscopy equipped with energy dispersive x-ray spectroscopy.The isothermal section constructed by [2010He] is shown in Fig.
