Nimonic 90 Rod is developed by replacing 20% of Ni in Nimonic-80A with cobalt. The addition of cobalt increases the solid solubility temperature of γ′. It also increases the solubility of carbon in the matrix and therefore influences the characteristics of carbide precipitation. The carbide dissolution temperature is lowered to about 900°C. Cobalt is a γ′ stabilizer and therefore imparts better high temperature strength. Both MC type and M23C6 type carbides are present in this material. The physical metallurgy of Nimonic alloys is given in ref. and the hot ductility studies are in refs.
Nimonic 90 is also known as Superimphy 90, Pyromet 90, and Udimet 90.
