摘要:
The isothermal section of the Y-Al-Sb ternary system at 800 K has been investigated mainly by powder X-ray diffraction (XRD) with the aid of differential thermal analysis (DTA), optical microscopy and scanning electron microscopy (SEM). It consists of 12 single-phase regions, 23 two-phase regions and 10 three-phase regions. The maximum solid solubility of Al in Y5Sb3 is about 27 at.%. No ternary compounds were found.
