Method for producing in situ metallic foam components

摘要

Disclosed is a method for producing a complex composite metal structure having a metallic foam substrate. A sheet metal structure is provided having a metallic foam precursor formed of metallic particles and foaming agents. The sheet metal structure is formed using quick plastic or superplastic formation processes. After or during the formation of the metal, the temperature of the metallic precursor is raised to a point that the foaming agent produces a metallic foam.
