Abstract
In this work several FeCoNi based nanocrystalline alloys were obtained by mechanical alloying Thermal study was performed by differential scanning calorimetry and thermogravimetry After 80 h milling all DSC scans show several reactions on heating At low temperature about 400 K the exothermal process detected is associated to structural relaxation In all alloys the main crystallization process begins over 700 K and has apparent activation energy values between 37 and 31 eV at–1 The Co content increases the thermal stability of this process Furthermore thermomagnetic measurements confirm the Co solid solution into Fe The ferromagnetic–paramagnetic transition occurs at about 900 K
