The influence of alloying on the mechanical properties of AA5083 type Al-Mg
alloy sheets produced by accumulative roll bonding (ARB) process was studied.
Two investigated Al-Mg alloys: commercial AA5083 alloy with 4.2% Mg, and modified AA5083 alloy with 5.1% Mg and addition of 0.5% Zn, were supplied by ImpolSeval Aluminium Mill (Sevojno, Serbia) as hot rolled thick plates. Hot rolled plates
were further laboratory cold rolled up to 1 mm in thickness, and ARB processed at
room temperature with ~ 50% reduction per each ARB cycle. It was possible to
conduct up to maximum 6 ARB cycles for a commercial AA5083 alloy and 4 ARB
cycles for modified AA5083 alloy.
Hardness and tensile properties of ARB processed multilayered sheets were
significantly improved with Mg and Zn addition. In the initial annealed state, before
ARB processing, yield strength of the modified AA5083 alloy was only 15-20 MPa
higher than for a commercial AA5083 alloy. However, flow stress level and tensile
streng...th became higher for nearly 100 MPa after each ARB cycle for the modified
AA5083 alloy in comparison with standard AA5083 alloy. The elongation decrease
value was high after the first ARB cycle, while after subsequent passes it stayed
almost constant, and slightly improved with Mg and Zn addition. Resistivity level
was also affected by chemical composition of the tested alloys. Higher resistivity
level obtained for the modified AA5083 alloy was attributed to higher Mg content
and addition of Zn.
Despite the fact that addition of Mg and Zn limited the possibility of joining
through ARB processing, mechanical properties of the modified AA5083 alloy were
superior over a commercial AA5083 alloy.
