摘要
The in situ observation of crystallization behavior of metallic glass Co_(65.1) Fe_(4.7)Ni_(4.6)Si_(10.2) B_(15.4)during heat-ing in an electron microscope is carried out. The three crystalline phases correlated with the exothermalpeaks on the DSC profiles are identified by means of electron diffraction. and they are all stable phasesfrom room temperature to 1000 K.Besides.an anomalous crystalline phase with long spikes along the direction in the reciprocal lattice space is found during crystallization. and its structural model is also discussed.
