Abstract

Using acoustic-resonance spectroscopy, we measured the monocrystal elastic-stiffness coefficients, the Voigt Cij, of TiB2. With hexagonal symmentry, TiB2 exhibits five independent Cij: C11, C33, C44, C66, C13. Using Voigt-Reuss-Hill averaging, we converted these to quasiisotropic (polycrystal)elastic stiffnesses. Briefly, we comment on effects caused by voids. From the Cij, we calculated the Debye characteristic temperature, the Gruneisen parameter, and the various sound velocities. Our study resolves the enormous differences between two previous reports of the Cij of TiB2.
