S 53 Shein, I. R. Elastic properties of carbide, nitride, and boride ceramics with WC-type structures [Текст] / I. R. Shein, D. V. Suetin, A. L.

Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: The elastic constants (Cij) of boride, carbide, and nitride (RuB, WC, WN, and TaN) ceramics with WC-type structures have been calculated using the full-potential linearized augmented plane wave (FLAPW) method with an exchange-correlation potential in the generalized gradient approximation (GGA). Numerical estimates of elastic parameters of the corresponding polycrystalline ceramics (bulk compression modulus, shear modulus, Youngis modulus, Poissonis ratio, and Lameis coefficients) of these ceramics are obtained and analyzed for the first time.
