Effect of Elastic Distortions Caused By Orowan Loops in an Infinite Anisotropic Medium on Moire Fringes

Abstract

The effect of the elastic distortions caused by the discrete Orowan loops surrounding alpha-Fe particle embedded in a Cu matrix on the rotation angles of the dislocation loop plane and Moire fringes was examined in terms of the anisotropic elasticity by using the numerical methods. For both isotropic and anisotropic cases, these angles were calculated depending on the shape of the dislocation loops. We arrived at the conclusion that, in order to explain the experimental rotation angles of Moire fringes, the anisotropic properties and the shape of the discrete Orowan loops should be taken into account.
