Abstract
A finite-element formulation which derives constitutive response from crystal plasticity theory is used to examine localized deformation in fee polycrystals. Thepolycrystals are (simple) idealized three-dimensional arrangements of grains, andmany elements per grain. Non-uniform deformations within individual grains leadto the development of domains that are separated by boundaries of high misorien-tation. Also, localized shearing is seen to occur on a microscopic scale of graindimensions. The important consequence of these simulations is that the predictedlocal inhomogeneities are meeting various requirements that make them possiblenucléation sites for recrystallization.
