Abstract

Equal-channel angular pressing is one of the best procedures for introducing an ultrafine grain size into a material. By using samples of pure Al, 7075 Al and 2021 Al as received and after annealing, by passing them through channel angle Ѳ, channel angle Ѳ is intersection of the two channels within the die on the subsequent. Experiments were performed using dies having channel angles from 110⁰ to 135⁰. dry sliding wear tests have been conducted using a pin-on-disk machine under different loads of 10, 20 and 30N at a constant sliding speed of 2 m/s. Comparison of strength and wear resistance of specimens shows that by using ECAP process, strength and wear resistance of the specimens increase considerably due to the formation of very fine grains during ECAP.
