ABSTRACT:
A method of superplastically forming aluminum alloy composites employs explosive bonding to produce strong, consistent bonds and annealing treatment to produce a fine microstructure in the bonded alloy sheets. The bonded alloy sheets having the fine microstructure can then be formed by superplastic methods to produce complex parts and structural elements.
