Abstract

The paper reports on a study to clarify the influences of restriction of grains and shape of grains on the deformation behavior of individual grains in polycrystalline metals having texture. The stress and strain in each grain in a rolled steel sheet during uniaxial elastic deformation were analyzed by the finite element method using a plane model of polycrystals, and the influence of texture on the elastic constants of the bulk specimen and that on the lattice strains in grains reflecting X-rays were discussed. It was found that the stress in a grain is affected by the condition of restriction of grains and the shape of grains. In the case of the model with a circular grain, the change in stress with crystal orientation becomes large when the deformation of each grain is strongly restricted. In the case of the model with an elliptic grain, the mode of deformation is close to the condition of uniform local strain and the influence of restriction of grains is small when the shape of grains is prolate in the direction of applied stress; the mode is close to the condition of uniform local stress and the influence of restriction is large when it is oblate. The elastic constants of the bulk specimen are affected by the texture, and their values are dependent on the condition of restriction of grains and the shape of grains. Additional study results are discussed.
