During plastic deformation of FCC materials, dislocation density does not evolve uniformly but a dislocation cell/wall structure is formed. X-ray diffraction reciprocal space mapping is used to investigate this substructure within a single grain in a large grained aluminium polycrystal. A simple disolcation cell/wall model capable of computing numerical reciprocal space maps is presented. The model qualitatively captures the experimentally observed features.The full-text of this article is not currently available in ORA, but you may be able to access the article via the publisher copy link on this record page
