A cast article having a reinforced structural composite core is disclosed. The cast article includes a structural element which is embedded in the otherwise cast metal article. The structural element is comprised of a metal matrix composite structural core. It includes a plurality of reinforcing fibers within a metal matrix. The fibers are generally a non-metallic material such as a ceramic which degrade at a temperature below the melting temperature of the cast metal comprising the article. The metal matrix composite structural core is encased with a sheath. The sheath, attached to and completely surrounding the core, is made of the same metal as the cast metal article. In a preferred embodiment, the article is a titanium alloy strut for a gas turbine engine.
