Abstract
Cast eutectic alloys on the basis of nickel aluminide of the equimolar NiAl-Mo (Cr, V, Nb) composition with alloyed additives of boron and hafnium have been produced by centrifugal SHS-metallurgy. It is found experimentally that the acceleration range of 150–200 g is the most readily producible. The convective movement of melt downstream of the combustion front under the effect of gravitation is shown to result in burning rate increase, com- plete chemical interaction in the combustion wave and composition homogenization in the combustion product melt volume. As established, the al- loys have composite structure of NiAl-grain with insignificant amount boride inclusions (MoВ, V(Cr)B, Mo(Nb)B2) uniformly distributed in the ground- mass consisting of β/γ-eutectics. The density does not exceed 6,7 g/cm3 for all four examined compositions.
