Abstract
The isothermal section of the phase diagram of the Al-Sb-Tb ternary system at 773 K was investigated mainly by means of x-ray diffraction, the Rietveld method, scanning electron microscopy (SEM), and energy dispersive x-ray spectroscopy (EDX) techniques. The existence of nine binary compounds AlTb, AlTb, AlTb, AlTb, AlTb, SbTb, SbTb, SbTb, and AlSb has been confirmed and no ternary compound was found. Binary compound SbTb is unstable in the present work. The solubility of the third component, Al, in the binary compound SbTb (MnSi type structure) was studied by SEM/EDX and the Rietveld method. Results of the experimental investigation of the Al-Sb-Tb system are compared with the integrated R-Al-Sb (R = Y, La, Pr, Nd, Dy) alloy systems and discussed. [ABSTRACT FROM AUTHOR]
