Abstract:
A joining method includes performing a first heat treatment step on a first superalloy workpiece and a second superalloy workpiece wherein at least one of the first and second superalloy workpieces include a gamma matrix phase and a gamma-prime precipitate phase. The first and second superalloy workpieces are joined using a solid state joining process, subjected to a post-weld stress relief operation and a final aging heat treatment.
