Isothermal section (400°C) of the phase diagram of Y–Al–Ga ternary system in the region up to 33.3 at.% Y

Electrical Resistivity of the Y(Ga,Al)$_2$, Y(Ga,Si)$_2$ and Y(Ga,Ge)$_2$ Solid Solutions with Structure of AlB$_2$ Type

“…[4][5][6][7], in the Y-{Al, Si, Ge}-Ga ternary systems, intermetallic YGa 2 forms substitutional solid solutions with homogeneity regions that extended along the 33.3 at.% Y isoline up to (at.%) 18 Al, 12 Si and 4 Ge, respectively. Moreover, the crystal structure of these solid solutions is characterized by the replacement of some gallium atoms in the graphite-like nets by atoms of the third component.…”

The quasi-binary system SmGa2–SmAl2 at 600ºC

“…Isothermal sections of the phase diagrams of ternary systems R-Ga-Al (R -rare-earth metal) have been constructed for the following rare-earth metals: Y, La, and Ce at 400°C in the region 0-33.3 at.% R [1,2], La at 400°C over the whole concentration range [3,4], Gd at 800°C in the region 20-100 at.% Gd [5,6], Ho at 500°C and 800°C in the region 25-33.3 at.% Ho [3]. For R = Ce [7], Nd [8,9], Eu [10], Gd [11], Er [8,9], Tm [12,13], and Yb [10,14] the quasi-binary sections RGa 2 -RAl 2 have been investigated.…”

Calorimetric study of enthalpies of mixing in liquid (aluminium–gallium–yttrium) alloys

“…Summarizing all aforementioned, the phase equilibria and thermodynamic properties of the ternary Al-Ga-Y system as a constituent of the quaternary Al-Ga-Y-TM family is of interest. Crystal structures of the intermetallide compounds, which form in the Al-Ga-Y system, have been examined by X-ray powder diffraction with Rietveld refinement in the region from (0 to 33.3) at.% Y [10]. Four rare-earth ternary intermetallide compounds have been found on the isothermal sections of the system at T = 673 K [10], namely: Y(Al x Ga 1 À x ) 4 (0.65 < x < 0.6875), Y(Al x Ga 1 À x ) 4 (0.4 < x < 0.475), YAl 0.4 Ga 2.6 , Y(Al x Ga 1 À x ) 2 (0.35 < x < 0.45).…”

In addition, regions of solid solution, which form with substitutions of Al on Ga and vice versa in the YAl 3 , YAl 2 , YGa 6 and YGa 2 intermetallide compounds, have been determined in the ternary system [10].…”

The magnetic susceptibility of the Y(Al x Ga 1 À x ) 4 compounds have also been reported in [11].…”
