摘要：
The microstructures of pure aluminum produced by equal channel angular extrusion (ECAE) with routes Be and C were characterized quantitatively by the use of transmission electron microscopy. A comparison with the results of cyclic-extrusion-compression reported in the literature is also presented, which indicates that ECAE is more effective in generating high angle boundaries.
