The alloyed powders were microstructurally characterized by X-ray diffraction (XRD). The thermal transformation of amorphous Mg50Ni50 into stable intermetallics (Mg50Ni50 -> remaining amorphous + Mg2Ni -> Mg2Ni + MgNi2) was analyzed using the Kissinger and iso-conversional methods based on the non-isothermal differential scanning calorimetry (DSC) experiments. The apparent activation energies (Ea) and the transformation diagrams, temperature-time-transformation (T-T-T) and temperature-heating rate-transformation (T-HR-T), were obtained for both processes. A good agreement was observed between the calculated transformation curves and the experimental data, which verifies the reliability of the method utilized. (C) 2009 Elsevier B.V.
