Abstract
The effect of trace element vanadium on the superplasticity of 5083 aluminium alloy sheets was studied by high temperature tensile optical microscopy. The results showed that trace element vanadium added into 5083 alloy could refine the fibrous structure of the rolling sheet, restrain the grain growth during recrystallization, and improve the superplasticity of 5083 aluminium alloy. The size of recrystallized grains of the sheets was reduced from 100 to 20 μm, and the elongation percentage of 5083 aluminium alloy sheets in 510°C was improved from 208% to 254% after the trace element vanadium was added into the conventional 5083 aluminium alloy.
