Abstract

Abstract: It was shown by TEM and X-ray analysis that Ni3Al is the main phase of the intermetallic synthesized under compression from the powder mixture of Ni with Al alloyed by B. The Ni3B is a secondary phase. The value of the lattice parameter of the intermetallic Ni3Al with and without B increases when the concentration of Al increases. The increase in Al concentration from 23.5 to 25.0 in the initial powder mixture leads to decreasing the solubility of B in the Ni3Al phase.
