Elastic atomic interaction in solid solutions ZrC-NbC-MoC1?x

The authors constructed a model illustrating the regularities of the change of physical properties on diagrams of composition vs property of the pseudoternary system ZrC-NbC-MoC/sub 1-x/. The investigations of the coefficient of thermal expansion, of thermal conductivity and electrical conductivity of the solid solutions ZrC-NbC-MoC/sub 1-x/ were carried out in the temperature range 1000-2300/sup 0/C. The obtained dependences of the coefficients of thermal expansion are easily reduced by simple linear extrapolation to their values at room temperature. As a result all the polynomial dependences of the above properties and also the dependence of the lattice parameter and of the modulus of normal elasticity are determined at the same temperature
