Abstract

Amorphous to crystalline transformation after isochronal annealing of as-quenched ribbons with the composition Fe73.5Cu1Nb1Si13.5B 9X2 (X = Zr, Nb, Mo, V) was investigated by the combined use of differential scanning calorimetry and Mössbauer spectroscopy. Alloying raises the thermal stability in the order V < Mo < Nb < Zr. The fraction of the Mössbauer subspectra corresponding to the nanophase for the same annealing conditions decreases in the order V > Mo > Nb > Zr.
