The microstructural changes of Fe_(83)Si_4B_(13) amorphous mother alloy during the heating process were investigated by Laser Scanning Confocal Microscopy( LSCM),and the phase transformation was determined by the Thermo-Calc calculations. The differences in the melting points measured by Differential Scanning Calorimetry( DSC)and LSCM,and those obtained by Thermo-Calc calculations were also discussed. It is found that the melting points measured by DSC and LSCM are relatively similar,whereas the onset and end of the melting temperatures calculated by Thermo-Calc software are higher than those measured by DSC and observed by LSCM.

The differences in the melting points measured by Differential Scanning Calorimetry (DSC) and LSCM, and those obtained by Thermo-Calc calculations were also discussed. It is found that the melting points measured by DSC and LSCM are quite similar, while the onset and end of the melting temperatures calculated by Thermo -Calc software are higher than those measured by DSC and observed by LSCM.
