摘要
The phase diagram determination of Al-Fe-Y is helpful for development of magnetic and amorphous materials. The entire isothermal section of Al-Fe-Y at 773 K has been determined by means of x-ray powder diffraction, scanning electron microscopy with energy dispersive analysis and optical microscopy. The existences of 14 binary compounds in the Al-Fe, Al-Y and Fe-Y binary systems were confirmed. The binary phases Al2Y, Fe2Y, Al2Y3, Fe23Y6 and Fe17Y2 in this study present appreciable ternary solubility: Fe17-x Al (x) Y-2 (0 a parts per thousand currency sign x a parts per thousand currency sign 8.5), Y(Fe1-x Al (x) )(2) (0 a parts per thousand currency sign x a parts per thousand currency sign 1), Al-2(Fe (x) Y1-x )(3) (0 a parts per thousand currency sign x a parts per thousand currency sign 0.3), and (Fe,Al)(23)Y-6 with Al up to 22 at.%. The ternary compounds: tau(1)-Al10Fe2Y, tau(2)-Al8-x Fe4+x Y (0 a parts per thousand currency sign x a parts per thousand currency sign 2) were confirmed. The isothermal section consists of 19 single-phase regions, 33 two-phase regions and 17 three-phase regions.
