Abstract
A novel method is provided for producing metallic glass reinforced metal rix composites possessing good interfacial bonding between the metallic glass and the metal matrix without gross degradation of the metallic glass or metal matrix. A layer of metallic glass in suitable form, e.g. ribbon, wire or flake, is placed between layers, e.g. sheets, of metal matrix material, which exhibits superplastic flow at a temperature below the crystallization temperature of the metallic glass material. The resulting structure is compressed at a temperature below the crystallization temperature of the metallic glass and sufficient to produce extensive superplastic flow of the metal matrix material.
