Non-isothermal crystallization kinetics and soft magnetic properties of the Fe67Nb5B28 metallic glasses
Differential scanning calorimetry (DSC) was used to investigate the thermal behavior and non-isothermal crystallization kinetics of the Fe 67 Nb 5 B 28 metallic glasses prepared by melt-spinning method. DSC traces exhibit that the crystallization takes place through a single exothermic reaction, and...
