The bulk elastic properties of polycrystalline graphite have been calculated using various averaging methods and compared with the properties obtained from the measurements of the longitudinal sound velocities, Static elastic modulus as well as the diffraction elastic modulus was measured by high resolution neutron diffraction. It was shown that the anisotropy of the elastic properties of reactor graphite is due to the crystallographic texture formed during the extrusion process.
