ABSTRACT

A commercial aluminum alloy AA 6061 was processed through equal channel angular pressing (ECAP) at 500 0C. The influence of ECAP on tribological properties and microstructure of the alloy was investigated. Experimental results showed that the grain size has reduced due to increase in dislocation density and the fraction of formed grains (sub-grains) after ECAP. Wear resistance of the alloy after ECAP was significantly improved. The loss of mass was reduced noticeably after single pass of ECAP process and increased with increase in load applied.
