摘要：

We synthesized for the first time the intermetallic compound Fe2MnGe. To avoid preferential evaporation of volatile components we exploited mechanical alloying. Amorphous Fe2MnGe alloy powder was prepared by planetary ball milling elemental starting materials. The amorphous-to-crystalline transition was studied by means of differential scanning calorimetry (DSC) and X-ray diffraction (XRD). A cubic D0(3) phase is formed at low temperature and transforms to a high-temperature hexagonal D0(19) phase. The apparent activation energy was determined by means of the Kissinger method.
