Abstract: It has been found that an addition of 0.5wt.% Cu in a commercial AA 5182 alloy reduces the alloy's hot formability. The decrease in ductility is related to the influence of Cu on the size of the Mn-bearing dispersoids. The addition of Cu effectively produces a larger number of small dispersoids, which retards the recrystallization. Consequently, the strain induced recrystallization which takes place during the hot deformation and inhibits the fracture propagation, is less present in the alloy with Cu. This is recalled to be the reason for its reduced hot ductility.
