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 grainrefinement process was more efficient. The results indicate that the NECAP test has some interesting features that may be of interest for further research.
