Effect of Sintering Temperature on Microstructure and Performance of Ti(C,N)-Based Cermets

Abstract:

In order to find a way which is low cost in preparation of Ti (C,N)/Fe composites. Ti (C,N)/Fe composites were prepared from TiFe (w (Ti)=30%), FeNCr (w (N)=5%,w (Cr)=60%) and toner by Vacuum Hot-pressed Sintering. The effect of sintering temperature on microstructure and performance of Ti (C,N)/Fe composites and the reason of it were studied. The results show that the Ti (C,N)/Fe composites prepared by Vacuum Hot-pressed Sintering have excellent performance, when the temperature was less than 1150°C, shrinkage rate of material was low,and reaction was slow. When the temperature was higher than 1150°C, material shrunk obviously,and reaction became faster, fracture toughness and bending strength rised rapidly at 1150°C-1200°C, rised slowly at 1200°C-1250°C, hardness was maximum at 1200°C.
