Abstract
Effect of microalloying by boron, added by two different methods, on the microstructure and martensitic transformation in as-cast and aged Ni54Fe19Ga27 alloys was studied. The increase of the aging time of the Ni54Fe19Ga27 alloy from 0.5 to 10 h at 823 K leads to the formation of a large volume fraction of the ordered γ′-phase. Microalloying with boron inhibits the precipitation of the γ(γ')-phase and prevents its ordering. The parameters of martensitic transformation are most stable with increasing aging time of a (Ni54Fe19Ga27)99.7B0.3 alloy when boron is added in the form of a NiB alloy.
