Isothermal sections of the Co-Al-Re ternary system at 1100 and 1300 ℃ were determined experimentally by electron probe microanalysis and X-ray diffraction. The results show that there are seven three-phase regions in the 1100 ℃ isothermal section and five three-phase regions in the 1300 ℃ isothermal section. The solid solubilities ofαCo,εRe and CoAl increase a little with temperature increasing from 1100 to 1300 ℃. The solubility of Co in compounds AlRe2, Al11Re4 and Al4Re is negligible,<1.5 at.%. And no ternary compounds are found.
