Effect of plastic deformation on microstructure and poperties of Al-Cu alloy

Microstructures and mechanical properties of as cast and as rolled Al-Cu alloys have been investigated. 3D micrographs of the as rolled alloy containing 10 wt.%Cu indicates that the shape of lead particles changes from globule-like to dishlike. The values of UTS and percent elongation for as rolled Al-Cu alloys maintain higher than that for as cast Al-Cu alloys. The wear tests show that to minimise the friction and wear, an optimum amount of about 15 wt.%Cu is desirable in the studied Al-Cu alloy.
