Abstract
The effects of a relatively high concentration of point defects on the elastic properties of a bcc crystal in the Elliott-Taylor approximation have been studied by using a defect perturbation model extending up to second neighbors. Numerical calculations have been performed for two experimentally studied Mo-Re (7 and 7.4%) alloys. It is observed that the changes in the second-neighbor force constants are very small and the perturbation may well be described by a nearest-neighbor defect model. The results obtained in the Elliott-Taylor approximation are seen to be very near to those obtained in the lowest-order concentration theory.Keywords
