| Popis: | We have used x-ray structural analysis, together with transmission and scanning electron microscopy, to study the phase composition, structure, and elemental distribution in the intermetallide Ni3Al+0.5 at.% B, produced by self-propagating high-temperature synthesis under pressure. It is shown that the synthesized material is an ordered alloy of the type L12. The phase composition of the alloy Ni3Al+0.5 at.% B is represented by the phases Ni3Al (the fundamental phase), grains of a layered NiAl composition, and inclusions of Ni3B. The latter is found inside the Ni3Al grains, in the form of surrounded particles, and at dislocations and at grain boundaries in the NiAl phase. |
