In classical simulation of abnormal grain growth, the microstructure is generally assumed to be homogeneous in size and the texture randomly distributed on such a theoretical microstructure which characterizes the primary recrystallized state. Experimentally, this last assumption could not be verified in Fe3%Si sheets (grade HiB). Consequently, a new simulation procedure has been implemented using a real microstructure measured by Orientation Imaging Microscopy (OIM) as an input data set. In this first work, the influence of the texture inhomogeneity has been analyzed from a theoretical point of view using Orientation Distribution Function (ODF) calculations and Monte-Carlo simulations without correlation with experimental measurements. The present paper deals with firstly the evolution of both microstructural and textural inhomogeneities and secondly the comparison, grain by grain, at several time steps of the experimental and simulated results obtained during secondary recrystallization.
