Fe73.5Cu1Nb3Si16.5B6 ribbons have been prepared by the melt-spinning technique, and subsequently submitted to different milling times (12-200 h). The samples have been microstructurally and magnetically characterized by X-ray diffraction, differential scanning calorimetry thermal analysis and vibrating sample magnetometer techniques, respectively. We found that the milling time induces nanocrystallization process and reduces the percentage of amorphous phase. Also, this structural change is accomplished by a progressive magnetic hardening. These results can be associated to the presence of residual stresses induced with grinding.
