摘要：
The rapid solidification microstructure and magnetic properties of melt-spun ribbons in the (Fe0.75P0.125C0.125)(100-x)Cu-x (at%) alloys were investigated, focusing on the occurrence of liquid-phase separation and simultaneous amorphous-phase formation. The (Fe0.75P0.125C0.125)(100-x)Cu-x alloys were designed as a combination of Fe-P-C alloy with high glass-forming ability and Cu. Amorphous-phase formation was observed in the melt-spun ribbons of the (Fe0.75P0.125C0.125)(100-x)Cu-x (x = 10, 20) alloys. For the melt-spun ribbons of the (Fe0.75P0.125C0.125)(100-x)Cu-x (x = 10) alloy, a composite of Fe-P-C amorphous matrix and FCC-Cu globules was obtained, whereas in the melt-spun ribbons of the (Fe0.75P0.125C0.125)(100-x)Cu-x (x = 20) alloy, multistep liquid-phase separation resulted in a particular solidification microstructure.
