Enhancing the High-Temperature Strength of a Co-Base Superalloy by Optimizing the g/g¢ Microstructure

Enhancing the High-Temperature Strength of a Co-Base Superalloy by Optimizing the g/g¢ Microstructure

Compositionally complex polycrystalline g/g¢ CoNi-base superalloys, such as CoWAlloy2 (Co41-Ni32-Cr12-Al9-W5-Ti0.3-Ta0.2-Si0.4-Hf0.1-C-B-Zr) are interesting candidates for new high-temperature materials. To maximize their high-temperature strength, the g/g¢ microstructure has to be...
