The Co–Ga–Si Ternary System at 870°K

Abstract

X-ray diffraction, structural, and metallographic analyses are employed to construct the isothermal section of the Co–Ga–Si ternary phase diagram at 870°K in the entire composition range. No ternary compounds form at the experimental temperature. A series of binary compounds are confirmed to exist. It is established that there are substitutional solid solutions based on CoSi and CoGa binary compounds. Their homogeneity ranges are determined.
