Abstract Scope |
3003 aluminium alloy plates were processed by Incremental ECAP up to 4 passes. The plates were evaluated in terms of microstructure, mechanical properties, anisotropy and formability. It is demonstrated that such a processing results in UFG microstructure with high fraction of high angle grain boundaries exceeding 60%. The plates exhibit in planar and through thickness isotropy which manifest by the independence of YS, UTS and rα -values on the testing direction and fairly uniform distribution of microhardness across thickness. The ability to deep drawing was also evaluated. showing that although the processed plates are slightly prone to wall thinning (typical for aluminum alloys), they are resistant to earing formation, which is one of the main technological problem in deep drawing. The combination of isotropic parameters, enhanced mechanical strength and suitable ability to deep drawing may yield attractive products with a considerable potential for further forming. |
