The Mo_2FeB_2-based cermets were prepared by vacuum liquid phase sintering process.Based on the orthogonal tests,the addition of C and Si in the cermets was studied with the tranverse rapture strength and hardness as the reference indicators,and the range and variance analyses were accordingly carried out.Moreover,the phase composition and microstructure of the as-sintered cermets were characterized by OM,XRD,SEM and EDS.The results show that the Si content has a significant effect on the hardness of Mo_2Fe...
