Description	Alloys Ni-22Al-0.24B and Ni-22Al-1B (at. %) were prepared by vacuum induction melting and then directionally re-melted in resistance furnace working on the principle of the Bridgman’s method. Final microstructures of alloys were dendritic after directional re-melting Coarse grains of the phase Ni3Al were oriented in direction of crystallisation and rows of mesh were situated between them in parallel. The mesh was composed of grains of the phase Ni3Al, which surrounded channels of (Ni) phase. Boron formed in the matrix isolated islands of eutectics. Change of the growth rate influenced the primary dendrite arm spacing according to linear equation in such a way, that the distance decrease with an increase of rate for both alloys. Increasing rate caused also changes of volume fractions of the present phases. Increases of fractions of coarse grain of the phase Ni3Al and eutectics were observed, while volume fraction of mesh decreased. This conclusion was identical for both alloys.
