In order to investigate the effect of boron additions in the magnetostrictive behavior of Fe72Ga28
alloy, this alloy was doped with 0.5, 1.0, 1.5 and 2.0 at.% of boron. The results have shown that
boron additions of 0.5 and 1.0% improve significantly the magnetostriction, the values being about
two-fold higher compared to the undoped alloy. Microstructural evaluations suggest that boron
additions suppress partially the D03 phase ordering, retaining the a-phase. Furthermore,
the increase of lattice parameters of the a and D03 phases indicates that boron enters
interstitially in the cubic lattice of these phases. Both effects are considered to be responsible
for the increased magnetostriction observed in the (Fe0.72Ga0.28)99.5B0.5 and
Fe0.72Ga0.28)99.0B1.0 alloys. VC 2011
