Effect of an Addition of Vanadium on the Mechanical Properties of the A6061 Alloy Deformed by Accumulative Roll Bonding

Abstract

The aims of this work are to examine the effect of Vanadium (V) addition on the microstructure and mechanical proprieties of A6061 aluminum alloy processed by the accumulative roll bonding method (ARB). The results show that with the addition of 0.1 or 0.2 wt.% V to the A6061 ARBed alloy, the synergistic improvement in ductility and strength was successfully achieved. Indeed, the improvement in resistance can reach 22% compared to the ARBed A6061 without vanadium addition; the slight drop in elongation recorded is mainly because of detachments at the interfaces. These improvements are due to the combined effects of segregation and solid solution strengthening by the addition of V and the effects of grain refinement by ARB.
