ABSTRACT
In trying to assess the future technological impact of these new materials, however, it is prudent to look beyond the rather narrow confines of the aerospace propulsion and structural interests and concepts for a larger view of potential applications. Mention has been made, for example, of the possible uses of eutectic composites in electrical devices. The InSb-NiSb system was mentioned as one in which needles of NiSb of high electrical conductivity act as finely dispersed metallic inclusions in a semiconducting matrix of InSb which permits large thermo-magnetic and galvanomagnetic effects. In an aligned eutectic of InSb-NiSb, one has a magnetoresistive device with important applications in a field plate. For specific demonstration hardware studies of metal matrix composites it is necessary to return to the area of prime current technical interest, in aerospace structures. The metal matrix is stronger, has better properties in more cases, and provides high temperature stability.
