Abstract

The elastic deformation of polycrystalline metals under uniaxial stress was studied microscopically using a plane model of polycrystals. The stress and strain in a round crystal embedded in a homogeneous medium were analyzed by the finite element method, and the elastic constants of the bulk specimen and the lattice strains in grains reflecting X-rays were calculated. It was found that the stress in a grain calculated with the present model changes from that of a uniform local stress model to that of a uniform local strain model according to the change of crystal orientation in regard to the direction of applied stress. The elastic constants of polycrystalline metals are affected by the condition of restriction of grains, and it is closely related to the extent of elastic anisotropy of crystal whether the influence is large or not. Other results are discussed in the paper.
