We investigate the free vibration mode for Nickel-base single crystal and directionally solidified (DS) superalloy cantilever plates using three-dimensional finite-element analyses. The elastic anisotropy had a significant effect on the eigenfrequency and eigenmode of plates. The rotation of the crystal axis around the [001] axis had a smaller effect at low frequencies but a significant effect at high frequencies. The deviation of the crystal axis in the plate had a significant effect on the eigenfrequency at low frequencies as well as at high frequencies. The bulk elastic modulus of DS plates derived by means of the Reuss average was effective in estimating the eigenfrequencies of DS plates. Eigenfrequencies of DS plates could also be predicted by averaging the eigenfrequencies of single crystals which comprise DS plates.
