Degassing Behavior and Solid State Reaction of Nano-Ti(CN) Base Cermets in Sintering

摘要：

　　The chemical composition and solid state reaction of the nano-Ti(CN) base cermets in different sintering temperature were studied.The total carbon and oxygen content in compact were declined gradually with the increasing of sintering temperature,the nitrogen content in compact began to decline above 1100℃,the peak of de-gassing of N2 was formed before the emergence of liquid phase,the decomposition of N2 was arisen acutely above 1500℃.Mo2C and TaC diffused and took part in solid state reaction with Ti(CN) above 900℃,the solid state reaction was finished below 1200℃.WC diffused and took part in solid state reaction with Ti(CN) above 1100℃,it was dissolved below 1250℃,there were only two phases,Ti(CN) and Ni(Ni+Co),in the alloy.
