Abstract
The paper studies a remelt temperature effect on the structural heredity of an alloy produced by centrifugal SHS metallurgy methods. An example of intermetallic NiAl grade highly alloyed with boron demonstrates that the alloy superheat temperature over 100 °C (from tmelt) during vacuum induction remelting causes a substantial enlargement of SHS alloy structural components and occurrence of segregations. All test samples of the alloy had a composite structure consisting of a substitutional solid solution NiAl matrix, reticular inclusions of τ-boride (Ni20Al3B6) and dispersion discharge of complex boride (Mo, Cr)B.
