Abstract
Recent work on a lightweight, elevated-temperature intermetallic-matrix composite (SCS-6 SiC/α2 Ti-14Al-21Nb), including investigations of fabrication techniques, microstructural characteristics and mechanical behavior, indicates that the material appears promising for a number of demanding applications. If successfully implemented, this material, or a derivative, will provide substantial weight savings in aerospace systems. To realize this potential, major challenges must be conquered—low-temperature ductility and environmental resistance must be improved, and the cost must be brought to competitive levels.
