摘要：
Amorphous to crystalline transformation after isochronal annealing of as-quenched ribbons with the composition Fe73.5Cu1Nb1Si13.5B9X2 (X = Zr, Nh, Mo, V) was investigated by the combined use of differential scanning calorimetry and Mossbauer spectroscopy. Alloying raises the thermal stability in the order V < Mo < Nb < Zr. The fraction of the Mossbauer subspectra corresponding to the nanophase for the same annealing conditions decreases in the order V > Mo > Nb > Zr.
