The total and partial densities of states, cohesion energy of the solid solutions, and charge states of the constituent atoms were evaluated. Interatomic interactions were analyzed using the semiempirical tight-binding method. The results were used to discuss the possible mechanisms of formation of ternary ZrN-based solid solutions and compare their chemical stability Полный текст |
