Recently, we have been developing Co/Ni superalloys for polycrystalline applications. The status of the alloys (around 1:1 Co/Ni content, 15Cr) will be reviewed along with their oxidation and mechanical behaviour. The oxide films obtained up to 1000h oxidation at 800C will be reviewed. It is also found that in low cycle fatigue, high lives are obtained at elevated temperatures all the way up to yield, which indicates that oxidation attack is unproblematic. The creep responses obtained will also be reviewed. Conventional processing routes appear to be practicable, along with grain boundary engineering.
