Grain-to-grain strain inhomogeneity and development of rolling textures in cubic metals

Abstract

An analysis was carried out into the occurrence of grain-to-grain strain inhomogeneity in plane strain deformation of cubic metals. In the analysis, homogeneous strain constituted the reference state, and the inhomogeneity was introduced through shear deformations which were allowed to occur simultaneously with plane strain in individual grains. Each of the three possible shear deformations was considered, and grain orientations at which these additional shears are favoured were determined. An evaluation is then carried out of the role of this grain-to-grain shear inhomogeneity in the texture development of rolled cubic metals.
