Abstract

This paper reviews the several powder processing techniques that have been applied to the fabrication of both monolithic aluminides and their composites. Attention is given to the active research at Rensselaer on reactive sintering and reactive hot isostatic pressing of elemental powders, hot pressing of prealloyed powders, and molding of powder-fiber-binder slurries. The application of one or more of these techniques to the following monolithic intermetallics is described: NiAl, Ni3Al, TiAl, NbAl3, Ta2Al, and TaAl3. Progress has occurred in fabrication of dense compacts, including some composites, from these aluminides.
