HIGH-STRENGTH SUPERALLOY JOINING METHOD FOR REPAIRING TURBINE BLADES

摘要

A method of repairing high-strength superalloy turbine blades and joining superalloy components is provided. A damaged region of the turbine blade is welded without preheating it. The welded turbine blade is then subjected to a hot isostatic pressing process. The method results in a repaired turbine blade that has a desirable microstructure and robust mechanical properties.
