摘要：
The phase equilibria were investigated and the particulate phase diagram of melting was constructed for the Ni-Al-Re system in the Re-content range 0.2-14 at. %. The structure and phase composition of Ni-Al-Re alloys were established to depend on the rhenium content. The limits for optimal component ratios, at which alloys have maximal melting temperature, were determined. The alloy structure was shown to have a composite structure, which consists of a metallic NiAl matrix and Re fibers.
