Strain history, microstructure and texture were studied in an aluminum alloy processed by the recently proposed process of non-equal channel angular pressing (NECAP). Comparison with alloy processed by equal channel angular pressing (ECAP) has been performed. A much finer microstructure was obtained in NECAP, showing that in this modified ECAP test the grain-refinement process was more efficient. The results indicate that the NECAP test has some interesting features that may be of interest for further research.
