Effect of 4% Cu Addition to Commercially Pure Aluminum Grain Refined by 0.15% V on its Mechanical Behavior, Fatigue Life and Strength

Abstract:

Aluminum and its alloys are the second used materials after steels due to their useful and attractive properties. In this paper, the effects of 4% copper addition to commercially pure aluminum grain refined by 0.15% vanadium are investigated. In particular, the effects of alloying on the mechanical behavior, fatigue life and strength are considered. The main objective of this study is to improve the mechanical strength and the fatigue strength of aluminum by refining its columnar microstructure. The obtained results show that the addition of 4% copper and 0.15%V to commercially pure aluminum significantly refined its grain size, and hence improve its mechanical strength as well as its fatigue life and strength.
