“…However, excessive Cu doping (e.g., 0.7 %) reduces the GFA and consequently, the critical diameter for glass formation is reduced to only 1 mm. As the Cu doping is increased to 1 %, bulk glass can no longer be formed, which is consistent with the previous results reported by other researchers925.…”

The glass-forming ability (GFA) of alloys with a high-solvent content such as soft magnetic Fe-based and Al-based alloys is usually limited due to strong formation of the solvent-based solid solution phase. Herein, we report that the GFA of soft magnetic Fe-based alloys (with >70 at.% Fe to ensure large saturation magnetization) could be dramatically improved by doping with only 0.3 at.% Cu which has a positive enthalpy of mixing with Fe. It was found that an appropriate Cu addition could enhance the liquid phase stability and crystallization resistance by destabilizing the α-Fe nano-clusters due to the necessity to redistribute the Cu atoms. However, excessive Cu doping would stimulate nucleation of the α-Fe nano-clusters due to the repulsive nature between the Fe and Cu atoms, thus deteriorating the GFA. Our findings provide new insights into understanding of glass formation in general.

“…So the crystallization kinetics of amorphous alloys have been studied extensively. Recently, several attempts have been made to investigate the influence of substituting various alloying elements in the Fe 73.5 Cu 1 Nb 3 Si 13.5 B 9 composition (P for B [12], Ag for Cu [13], Au for Cu [14], Co for Fe [15], Cr for Fe [16,17]) on the crystallization process and magnetic properties. Generally, the crystallization kinetics of amorphous alloys have been studied by means of isothermal crystallization kinetics that can be analyzed using the Johnson-Mehl-Avrami method [18].…”
