MECHANICAL-PROPERTIES OF 2-PHASE MATERIALS - SINGLE-CRYSTALS WITH LARGE INCLUSIONS

The influence of a large inclusion in the deformation behavior of a si nge crystal of copper is addressed in the current presentation. The us ual assumption is that, provided that the inclusion is larger then the crystal sizes in a polycrystal, the matrix will deform following pret ty much the continuum mechanics solutions, whether them are isotropic of anisotropic, it is expected that big inclusions will act as interna l constraints to be treated as much as boundary conditions. in the cur rent investigation a regular distribution of W wires (.38 mm in diamet er) were used as reinforcement of Cu single, bi- and tri-crystal matri ces. The resultant composite was deformed by channel die perpendicular ly to the wires axes in two steps. The original orientation and after deformation resultant textures were measured by using x-ray texture me asurement techniques. Some previously published FEM calculations and t exture analysis were applied to the data for modelization of textures by a Taylor based model.
