The formation of the nanocrystallites (about 7-8 nm at 80h MA) was detected by X-ray diffraction. After milling for 80 h, differential scanning calorimetry scans show low-temperature recovery processes and several crystallization processes related with crystal growth and reordering of crystalline phases. The apparent activation energy values are 315 ± 40 kJ mol<sup>–1</sup> for alloy A, and 295 ± 20 kJ mol<sup>–1</sup> and 320 ± 25 kJ mol<sup>–1</sup> for alloy B. Furthermore, a melt-spun Fe-based ribbon was mechanically alloyed to obtain a powdered-like alloy. The increase of the rotation speed and the ball-to-powder weight ratio reduces the necessary time to obtain the powdered form.}, number={3}, journal={Revista de Metalurgia}, author={Suñol, J.
