In the magnetic sheets Fe–3%Si of HiB type, with AlN and MnS inhibitors, the Goss texture is obtained by a sudden and fast
growth of the small size
grains, with Goss orientation {110}

. This behaviour is not in good agreement with the classical
laws of
grain growth. In the present study, the abnormal
grain growth is related to the material texture and to the texture component evolution, by carrying out Monte Carlo simulation. The onset of abnormal
growth of Goss
grains seems to be linked to the existence of a favourable crystallographic neighbourhood. The
grains that grow abnormally do not have a size greater than the average size in the matrix; their ability to grow in an abnormal way can be related to the behaviour of
grain boundaries, which surround them. The
growth of a given
grain is controlled by the local evolution of
grain boundaries around that considered
grain and not by the average evolution of the totality of the matrix; the whole effect of the matrix can hide the effect of matrix heterogeneity. The experimental characterisation of matrix parameters is performed by Electron Back Scattering Diffraction (EBSD).
