摘要：

The phase relationships in the Al-Zr-Y ternary system at 773 K have been investigated mainly by means of X-ray powder diffraction (XRD) and scanning electron microscopy (SEM) with energy dispersive analysis (EDX). The 13 binary compounds, i e. AlZr(3), AlZr(2), Al(2)Zr(3), Al(3)Zr(4), AlZr, Al(3)Zr(2), Al(2)Zr, Al(3)Zr, alpha-Al(3)Y, Al(2)Y, AlY, Al(2)Y(3) and AlY(2) have been confirmed The Isothermal section of the Al-Zr-Y ternary system at 773 K consists of 16 single-phase regions, 29 two-phase regions and 14 three-phase regions No ternary compound is found in this work.
