摘要
Finite element simulations are used to study intracrystalline lattice misorientations in a model polycrystal. Heterogeneous deformations arise from crystal interactions and lead to irregular substructures exhibiting misorientations across their boundaries. The highest misorientations occur on interfaces that are normal to the principal loading direction. (C) 2002 Published by Elsevier Science Ltd. on behalf of Acta Materialia Inc.
