摘要：
The phase relations in the Al-Dy-Zr ternary system at 773K have been investigated by X-ray powder diffraction (XRD) and scanning electron microscope (SEM) with energy disperse X-ray spectroscopy (EDX) in backscattered electron imaging (BSE) modes. The isothermal section at this temperature is featured with 17 single-phase regions, 32 two-phase regions and 16 three-phase regions. Besides, the ternary compound Al(30)Dy(7)Zr(3) has been confirmed to be existed. The maximum solid solubility of Zr in AlDy(2), Al(2)Dy(3), AlDy, Al(2)Dy and Al(3)Dy at 773K is determined to be 11.5 at.%, 7.8 at.%, 2.4 at.%, 22.5 at.% and 2.5 at.%, respectively.
