Abstract
A metal structural component (10) is formed by placing metal tubes (16) between two metal sheets (12) and plastically deforming the tubes (16) by injecting pressured gas therein. The injected gas expands the tubes by superplastic deformation until diffusion bonding occurs between the metal sheets (12) and expanded tubes (16) to form the desired support structure between the metal sheets (12).
