Abstract: Ti(C,N)-based ceramics is a kind of hard material with a great development potential. The welding between ceramics and metal materials (steels et al) with high toughness can utilize the respective advantages and make work pieces meet the requirements under harsh working conditions, such as high hardness, high wear resistance, high strength and toughness and other excellent comprehensive performances. The high residual stress is the main problem during the welding of cermets and steels. In this paper, the research status on the stress state and distribution and stress relief mode of brazing joint of cermets(ceramics)/steels are reviewed at home and abroad. On the basis of the review, it is presented that the ceramicsw near the weld is the key area to relieve residual stress of the joints, and the stress relief research should be extended from the current solder to the near weld zone of ceramics.
