Abstract
Potential applications of superplasticity for lightweight metal foams are reviewed in this paper. Metal foams have been used for lightweight structures, biomedical implants, filters, heat exchangers, sound absorbers and mechanical damping devices. Superplasticity has advantages on metal foaming process and mechanical properties of metal foams. Four examples of metal foams combined with superplastic forming are presented; (i) Enhanced foaming under internal stress superplastic condition, (ii) Superplastic diffusion-bonding of metal foams, (iii) Superplastic forming and foaming and (iv) Superplastic Zn-22Al alloy foam for energy absorbing material.
