Abstract
A composite turbine disc includes a high nickel rim section and a steel bore section. The rim section is formed from a high nickel alloy which provides a higher melting point as compared to the material used for the bore section. A plating or forged welding enhanced agent layer is disposed between the bore section and rim section. Composite disc can be formed by forging the rim and bore material together, or by welding the rim and bore material together.
