| Abstract: | Two groups of Ti(C,N)-based cermet with different TiC powder sizes were prepared by powder metallurgy method using vacuum sintering process.The phase structure and microstructure were investigated by means of XRD,SEM and EDX,and the mechanical properties were tested at room-temperature as well.The results show that the cermet made from nano TiC powder offers fine and homogeneous structure and higher bending strength and hardness,being as high as 1021.5 MPa and 17.7 GPa(HV10) respectively. |
