From these single-crystal elastic constants the isotropic elastic moduli are calculated using the Voigt and Reuss averages. The calculated values are in fair agreement with the experimental values. The implications of the results are discussed with regards to Poisson's ratio and the direction dependence of Young's modulus.Materials scienceMetallurgyMetallurgical engineeringConference proceedingA1997BJ28E00093N/A6091
