| Abstract: | The valence electron structures of the ternary composite phase (Ti,Mo,W)C, the quaternary composite phase (Ti,Mo,W,Nb)C,(Ti,Mo,W,Ta)C and the quinary composite phase (Ti,Mo,W,Nb,Ta)C in cermets have been calculated by means of the empirical electron theory of solids and molecules. The relation between the valence electron structure of ceramics and the bending strength of cermets is discussed. Based on the above relation, a criterion for the bending strength is proposed, and the bending strength tests have also been conducted to prove the correlation. |
