摘要：

The knowledge of thermal behaviour of materials is important in order to control their structure and properties. In nanocrystalline materials obtained from amorphous alloys, the knowledge of the crystallization kinetics permits to design special thermal treatments to develop materials with specific microstructure. The milling of melt-spun ribbons is a two-steps procedure to develop new nanostructured materials. Two, Co and Fe rich, melt-spun alloys were obtained and mechanically alloyed in low energy milling conditions, and their structure and thermal behaviour was analyzed. The thermal study was performed by means of differential scanning ealorimetry. All experimental curves are derived from non-isothermal calorimetric experiments. Good agreement is observed between the transformation curves and the experimental data, which verifies the reliability of the approach and the validity of the rate constant model description.
