The nature of the isothermal region of the Al–Mo–Gd ternary system at 773 K has been established by analysis of quenched samples, annealed for 6 weeks, by use of x-ray powder diffraction and scanning electron microscopy equipped with energy-dispersive analysis. Two ternary phases, Al 43 Mo 4 Gd 6 and Al 4 Mo 2 Gd were observed. Ten binary phases, including Al 17 Mo 4 rather than Al 4 Mo, were present at 773 K in the Al–Mo system. The ranges of homogeneity of the AlMo 3 and Al 8 Mo 3 phases were 7.5 and 1 at.%, respectively. According to results obtained from the disappearing-phase method, the maximum solubility of Al in Mo is approximately 16 at.%.
