Abstract
The present investigation was conducted to study vacuum brazing between carbon-carbon composites (CC) and TiAl alloys with Ag-Cu-Ti filler metal. The mutual exclusion between the Ag and Ti elements had a significant influence on the joint microstructure. The isothermal solidification of the Ag-based solid solution led to a layered microstructure, which was beneficial to the joining strength. A new method of making holes in the CC composite surface was introduced, and the joint was strengthened by the infiltration of filler metals into these holes.
