Abstract
A method of inertia friction welding a superalloy substrate, the method including: rotating and forcing a deposit material () against the superalloy substrate (); plastically deforming at least one of the deposit material () and the superalloy substrate () to form a weld joining the deposit material () to the superalloy substrate (), 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.
