Abstract:
A method of inertia friction welding a superalloy substrate, the method including: rotating and forcing a deposit material (110) against the superalloy substrate (100); plastically deforming at least one of the deposit material (110) and the superalloy substrate (100) to form a weld joining the deposit material (110) to the superalloy substrate (100), thereby forming an assembly; and heat-treating the assembly. Heat-treating includes: a post-weld intermediate stress-relief (ISR) treatment; a solutionizing treatment; and a precipitation hardening heat treatment.
