Abstract

The influence of the remelting temperature on the structural heredity of the alloy fabricated by centrifugal SHS metallurgy is investigated. It is shown by the example of the highly boron-alloyed NiAl-based alloy that overheating the alloy by more than 100°C (above Tm) during vacuum-induction remelting leads to substantial coarsening of the components of the SHS alloy and liquation appearance. All the samples of the alloy under study had a compositional structure consisting of the matrix of the NiAl-based substitutional solid solution, network inclusions of τ-boride (Ni20Al3B6), and dispersion inclusions of (Mo, Cr)B complex boride.
