Beschreibung
Zusammenfassung:	A process for the manufacture of repair material. The repair material is ductile and readily mechanically deformed and can be used in the repair of turbine components. The process comprises providing a directionally solidified material, cold-swaging the directionally solidified material, and heat treating the cold-swaged material into the repair material. The repair material, after the steps of cold-swaging and heat treatment, comprises a microstructure that is essentially free from cracks, for repairing the turbine component. The invention also sets forth methods for repair of articles, such as turbine components, using the repair material, and a turbine component repaired using the repair material.
