Summary

The objective of this study was twofold. On one hand the evolution of structure and hardness of IF steel with strain was followed up to an effective strain of 9.2 for route BA, in order to study the grain fragmentation at large strains. On the other hand the 4 classical ECAE routes A, BA, BC and C were compared at an effective strain of 9.2, in order to study the influence of the strain path followed during severe plastic deformation. Automated EBSD measurements were used because they allow to obtain a large collection of orientation data in a relatively short time with a fair resolution.
