dc.description.abstractLas aleaciones magnéticas nanoestructuradas a base de FeCo se destacan entre las aleaciones magnéticas convencionales a base de Fe por presentar óptimas propiedades magnéticas blandas, requeridas en una variedad de aplicaciones tecnológicas, industriales y biomédicas. En este trabajo se presentan los resultados obtenidos de la caracterización térmica por calorimetría diferencial de barrido y termogravimetría magnética de polvos puros de Fe y Co, y de polvos magnéticos nanoestructurados a base de Fe50Co50 y Fe65Co35 preparados por el método de Aleado Mecánico de elevada energía. Por medio de estas técnicas y bajo la influencia de diferentes atmósferas inertes como Helio (He),Nitrógeno (N2) y Argón (Ar), se evidenciaron los eventos térmicos que tienen lugar desde temperatura ambiente hasta 900 °C para muestras molidas a diferentes tiempos (0, 10, 15, 20 y 25 horas), eventos tales como las temperaturas de transición magnética y de orden – desorden características de este tipo de muestras y del proceso de moliendaspa
dc.description.abstractIron-cobalt based nanostructured magnetic alloys stand out among conventional magnetic Fe-based magnetic alloys because they exhibit the optimum soft magnetic properties required in a variety of technological, industrial and biomedical applications. In this work, the thermal characterization by differential scanning calorimetry was carried out using thermogravimetric analysis and magnetic thermogravimetry of Fe and Co pure powders, and nanostructured magnetic powders based on Fe50Co50 and Fe65Co35 prepared with the high energy mechanical alloying method. By means of these techniques and with the influence of different atmospheres as Helium (He), Nitrogen (N2) and Argon (Ar), thermal events for samples milled at different times (0, 10, 15, 20 and 25 hours) were evidenced taking place from -70 °C to 500 °C by differential scanning calorimetry and ambient temperature up to 900 °C in the thermogravimetric analyzer. The observed events, as the temperature in the material varies, are associated with the magnetic transition temperatures, order -disorder phase transitions and stress relaxation effect which are features of this type of samples and the milling processeng
