Al-3.9wt.%Cu alloy was subjected to equal channel angular pressing (ECAP) and subsequent low temperature annealing treatment, and the corrosion resistance of the samples was investigated by potentiodynamic polarization measurements in 3.5% NaCl solution. The results show that the corrosion rate of the ultrafine-grained alloy increases, in comparison with the coarse-grained alloy. Meanwhile, it is noted that the corrosion resistance of the alloy subjected to ECAP can be improved by relief annealing.

Al-0.6%Cu alloy processed by equal channel angular pressing (ECAP) was investigated in this study. The samples processed with 1, 2 and 4 ECAP passes were annealed at different temperatures. And the microstructures of the Al-0.63%Cu alloy samples were observed. The results show that the grains of the alloy are refined to sub-micron level after multipass ECAP. Moreover, it is found that the recrystallization temperature of the Al-0.6%Cu alloy samples decreases with increasing the number of ECAP passes. Based on the study above, effect of cold rolling reduction and ECAP passes on recrystallization temperature of materials should be further investigated.

In the present work a comparative study was carried out on consolidation of Al-5083 alloy and 5wt. % nanoyttrium oxide powders by Equal channel angular pressing (ECAP). The powders were milled for 10, 15 and 20 hrs using planetary ball mill under optimized process parameters. The milled powders were characterised by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Milled powders exhibit nanocrystalline single phase after 10hrs. The crystallite size after 20 hr of milling, alloy and composite powders were found to be 23nm and 57nm respectively. The 20hr milled alloy and composite powder was consolidated by equal channel angular pressing (ECAP) through 90o die channel angle using route-A for two passes with and without back pressure. Density of ECAPed samples were measured using Archimedes principle. The highest density was found as 96% for the alloy after 2 passes without backpressure and sintering and 94% for the composite after 2 passes with back pressure and sintering.
