The main advantages of the invention are mainly embodied in the following points:
1) near net shape of TiAl alloy
Taking the manufacture of a welding composite plate of TiAl alloy and ceramic as an example, the traditional process flow needs to obtain the TiAl alloy by smelting, then the TiAl alloy is manufactured into a plate by cogging forging and sheath rolling, and then the plate is brazed with a ceramic plate in vacuum. The TiAl alloy has large brittleness, extremely difficult hot rolling of plates and extremely low yield, so the whole manufacturing and processing difficulty of the technical process is large. The invention can be formed into a plate by powder cold pressing, thereby avoiding the processing difficulty of one side of the TiAl alloy.

In the aspect, the excessive liquid phase generated in the liquid phase activation sintering process of the TiAl alloy is innovatively utilized and used as an active solder in the welding process, and meanwhile, the densification and the connection with the ceramic material of the TiAl alloy are realized. The process avoids secondary heating and additional brazing filler metal in the vacuum brazing process, realizes optimization from two aspects of manufacturing cost and simplified process flow, and has strong application and popularization significance.
