The abnormal grain growth is related to the material texture, in the magnetic sheets Fe3%Si of HiB type, with AlN and MnS inhibitors. The onset of abnormal growth of Goss grains seems to be linked to the existence of a local favourable crystallographic neighbourhood. The grains which abnormally grow 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 local evolution around that considered grain, the whole effect of the matrix can hide the effect of matrix heterogeneity.
