Composition optimization of Fe-based bulk metallic glass based on multi-scale research
Glass formation is always a competitive process between the liquid phase and potential precipitation phase,which means that both the stability of liquid phase and the formation of competing crystalline phases should be considered for obtaining bulk metallic glass (BMG) with large glass-forming ability (GFA).Low melting point indicates a stable liquid state for specific system.Another important factor that is the tendency of crystallization should be associated with pre-precipitation phases.The selection principles for pre-precipitation of solution phase,which is the greatest obstacle to glass formation,were discussed by density functional theory (DFT) method.
