摘要：

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. (C) 2010 Acta Materialia Inc.
