Elastic-Stiffness Coefficients of Titanium Diboride

Using resonance ultrasound spectroscopy, we measured the monocrystal elastic-stiffness coefficients, the Voigt C(ij), of TiB(2). With hexagonal symmetry, TiB(2) exhibits five independent C(ij): C(11), C(33), C(44), C(12), C(13). Using Voigt-Reuss-Hill averaging, we converted these monocrystal values...

description Using resonance ultrasound spectroscopy, we measured the monocrystal elastic-stiffness coefficients, the Voigt C(ij), of TiB(2). With hexagonal symmetry, TiB(2) exhibits five independent C(ij): C(11), C(33), C(44), C(12), C(13). Using Voigt-Reuss-Hill averaging, we converted these monocrystal values to quasiisotropic (polycrystal) elastic stiffnesses. Briefly, we comment on effects of voids. From the C(ij), we calculated the Debye characteristic temperature, the Grüneisen parameter, and various sound velocities. Our study resolves the enormous differences between two previous reports of TiB(2)’s C(ij).
