Effect of equal channel angular pressing die angle on corrosion behavior of bulk nanostructured metal

Equal channel angular pressing technique was used to process bulk nanostructured commercial pure titanium Cp2(Ti Cp2) and aluminium alloy 6061(Al6061). The samples were processed at two different die channel angles of 120 º and 126 º. Hardness test shows that the hardness for Al6061, using channel...

Hardness test shows that the hardness for Al6061, using channel angle 120° ECAP-ed, has increase 15.55% while using channel angle 126° the increase was 14.89% compared to non-ECAP-ed sample.
