Abstract
Phase relations in the Al-Co-Y ternary system at 1173K have been established by means of scanning electron microscopy (SEM), electron probe microanalysis (EPMA) and X-ray diffraction (XRD) techniques. Isothermal section at 1173K of this system was constructed, which consists of 27 three-phase regions and 50 two-phase regions (27wider+23line). The ternary compound τ5-AlCo2Y2 has been confirmed to exist and the crystal structure has been preliminarily analyzed with pattern indexing method as well. The intermetallic phase Co2Y, Co3Y, Co7Y2, Co5Y, Co17Y2, Al2Y, τ4-AlCoY and τ5-AlCo2Y2 were expressed as the formula of AlxCo2−xY, AlxCo3−xY, AlxCo7−xY2, AlxCo5−xY, AlxCo17−xY2, Al2−xCoxY, Al1+xCo1−xY and Al1−xCo2+xY2, respectively.
