Abstract
The X-ray elastic constants of sintered polycrystalline alumina (with 99% purity) were measured for the diffraction planes (1. 0. 10) and (220) by using Cr-Kα radiation and for (146) and (4. 0. 10) by using Cu-Kα radiation, and the results were compared with the theoretical values obtained from the elastic constants of a single crystal on the bases of Reuss and Voigt models. The measured value of E/(1+ν) (E=Young's modulus, ν=Poisson's ratio) got smaller in the order of (146), (1. 0. 10), (220), (4. 0. 10). This order agreed with the theoretical prediction, although the value itself was smaller than the predicted value. Further comparsion of E and ν between the theory and the experiment indicates a necessity for making a suitable polycrystal model including the second phase or pores.
