Add to ORKGInternational audienceThe Co-30wt.%-xC system was experimentally explored from x=0 to 2wt.%, by considering the stable microstructures at 1,000, 1,100 and 1,200°C, and the intervals of fusion. The strengthening potential and the refractoriness of several alloys belonging to this family were specified. Such simple alloys are able to display simultaneously a high amount of chromium for limiting hot corrosion, solidus temperatures as high as 1,300 °C and refractory carbides fractions that can reach 20 % in volume. Natures and fractions of carbides, and solidus temperatures were in good agreements with thermodynamic calculations. Inversely the measured liquidus temperatures were significantly higher than the calculated ones. In addition, thermo...
