Abstract: Діаграма фазових рівноваг потрійної системи Y-Cu-Ge побудована за 870 К методами рентгенівської дифракції, металографічного аналізу і енергодисперсійної рентгенівської спектроскопії в повному концентраційному інтервалі. Встановлено утворення шести тернарних сполук YCuGe (структурний тип LiGaGe), YCu2Ge2 (структурний тип CeAl2Ga2), Y3Cu4Ge4 (структурний тип Gd3Cu4Ge4), Y2CuGe6 (структурний тип Ce2CuGe6) YCu0.67Ge1.33 (структурний тип AlB2) і YCu0.3Ge2 (структурний тип CeNiSi2).
The phase equilibrium diagram of the Y-CuGe ternary system was constructed at 870 K by X-ray diffractometry, metallographic and electron probe microanalyses over the whole concentration range. Formation of six ternary compounds YCuGe (LiGaGe-type), YCu2Ge2 (CeAl2Ga2-type), Y3Cu4Ge4 (Gd3Cu4Ge4-type), Y2CuGe6 (Ce2CuGe6-type), YCu0.67Ge1.33 (AlB2-type), and YCu0.3Ge2 (CeNiSi2-type) were observed.
