Abstract
A process is provided for manufacturing and repairing components, and particularly superalloy components such as gas turbine engine components. The invention entails forming precipitates in a surface of the article that has been cold worked as a result of surface machining, cleaning, handling, etc. The precipitates serve to prevent recrystallization and formation of a secondary reaction zone in the cold worked surface of the superalloy when subsequently exposed to temperatures approaching the solution temperature of the superalloy, such that the microstructure and mechanical properties of the superalloy article are preserved.
