Abstract
The influence of partial substitution of Fe. Si and B elements by Al (up to 9%) is analyzed for
a nanocrystalline FeSiBNbCu alloy. Structural studies show that the increment of Al deteriorates the glass forming
ability of the material. Coercivity in amorphous as-quenched samples becomes lower as the Al content increases in
two alloy series : while after nanocrystallization values as small as about 0.5 A/m are obtained.
DSC thermograms show that addition of Al advances the nucleation of the crystalline phase. Also, a
particular evolution is noticed when Si is replaced by Al : the exothermic peak characteristic of
α(Fe,Si) phase begins to split into two peaks while increasing the Al content.
