Abstract

The crystallization behavior of melt-spun A85Y10Fe5−xNx (x=0, 2.5, 5) amorphous alloys has been investigated by a combination of differential scanning calorimetry (DSC) and x-ray diffractometry (XRD). XRD traces of these alloys consisted of a single broad peak corresponding to fully amorphous structure. Continuous DSC results showed that, the first crystallization peak temperature of Al85Y10Fe5 amorphous alloy was about 60 K higher than that of Al85Y10Ni5. The activation energies for the first crystallization peak increased from 210 kJ/mol for Al85Y10Ni5 to 280 for Al85Y10Fe5. These results indicate that 5 at.% substitutions Ni by Fe increases the stability of the amorphous phase.
