Abstract
Niobium aluminide-based intermetallic matrix composites are currently being considered as potential high-temperature structural materials. One of the key factors in the selection of a reinforcement material is its chemical stability in the matrix. In this study, chemical interactions between two niobium aluminides, Nb3Al and Nb2Al, and several potential ceramic reinforcement materials, which include carbides, borides, nitrides, and oxides, were analyzed from thermodynamic considerations. Several thermodynamically stable reinforcement materials have been identified for these two matrices.Keywords
