Effect of 4% Cu Addition to Commercially Pure Aluminum Grain Refined by 0.15% V on its Ductility and Surface Roughness

Abstract:

In this paper, the effect of addition of 4%wt. copper to commercially pure aluminum grain refined by 0.15% vanadium on its grain size, hardness, ultimate tensile strength, UTS, ductility and surface roughness is investigated. It is found that when they are added individually or together causes pronounced reduction in grain size, i.e., effective refiners. Similarly, they increase its hardness and ultimate tensile strength but reduce its ductility. Regarding their effect on the surface quality, they enhance the surface quality if added individually. However, they reduce it if added together, i.e. they increase its surface roughness.
