Research Institution
Many properties of intermetallic compounds (IMC's) would make them strong candidates for vehicle structures, tankage, secondary structures, and appendages for NASA exploration systems. This includes excellent specific strength, creep, and oxidation resistance. However, the lack of ductility in these IMC's generally does not allow these materials to meet the design requirements for those vehicle structures. On the other hand, base alloys themselves, such as Ti-6Al-4V or Inconel, have sufficient ductility, but do not have the other desired attributes. Using a novel fabrication technique (plasma transferred arc solid free form fabrication, or PTA SFFF), MER will develop composite materials of IMC's with a strong, ductile base metal. These composite materials will have a combination of overall properties that cannot be obtained today in an IMC structure. The PTA SFFF process has the capability to scale up these composites to the large shapes required for vehicle structures.
