SUPERALLOY COMPONENT BRAZE REPAIR WITH ISOSTATIC SOLUTION TREATMENT

摘要

A method of braze repair for a superalloy material component. Following a brazing operation on the superalloy material, the component is subjected to an isostatic solution treatment, followed by a rapid cool down to ambient temperature under pressure The conditions of the isostatic solution treatment combined with the cool down at pressure function to both reduce porosity in the component and to solution treat the superalloy material, thereby optimizing superalloy properties without reintroducing porosity in the braze.

1. A method comprising:
applying a braze material to a superalloy component at a brazing temperature; holding the component at a temperature below the brazing temperature at a pressure above ambient for a time effective to reduce porosity in the component and to place a target constituent of the superalloy material into solid solution, and rapidly cooling the component while maintaining the pressure above ambient.
