摘要：
Crystallization and melting behaviors of the Nd60Al10Fe20Co10 bulk metallic glass (BMG) have been studied by differential scanning calorimetry (DSC), scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS). It is found that the BMG exhibits a melting process before the crystallization when the heating rate is larger than 20 K/min and the anomalous melting and crystallization behaviors are attributed to the partially melted phase due to primary crystallization. The kinetics of the main crystallization exclusive of the effect of melting process is studied by subtracting the heating behaviors from the DSC traces of the as-cast rod.
