Abstract

The study of deformation properties of low carbon steels is of particular interest because of their many technological applications. Obtaining fine grain Fe based materials can be approached by one of the several available Severe Plastic Deformation techniques. The current paper shows experimental data and simulations of the deformation process of Fe samples by Equal Channel Angular Processing. The samples were extruded in a 120o channel die either by one or a few passes. The heterogeneity and local development of the deformation on the elbow of the channel has been studied by X-ray measuring and simulation of the texture evolution. The Self Consistent models used for simulation allowed the calculation of the spin of the main texture components which agreed pretty well with the experiments.
