Abstrakt

Phase relations in the ternary system Al-Ru-Ti were studied on arc-melted alloys and specimens annealed at 1100 °C, 950 °C, and 800 °C employing optical and electron microscopy, x-ray diffraction, and electron probe microanalysis. The results, in combination with an assessment of all literature data available, were used to construct liquidus and solidus surfaces, a series of isothermal sections, and a Schulz-Scheil diagram monitoring solidification (crystallization) in thermodynamic equilibrium. The crystal structure of the ternary G-phase was determined by x-ray single crystal diffraction to be a filled variant of the Th₆Mn₂₃-type (space group Fm3¯m). Furthermore, a new ternary compound with AuCu ₃-type structure was detected.
