英文摘要	Liquid-liquid phase separation was used to design phase-separated metallic glasses with special properties. In this work, Zr60Cu40-xFex phase-separated metallic glasses were designed by partial substitution of Cu by Fe in Zr60Cu40 metallic glass. The liquid-liquid phase separation behavior of Zr60Cu40-xFex alloy was investigated. The results show that the miscibility gap of the binary Cu-Fe system can be extended into the Zr60Cu40-xFex system and that liquid-liquid phase separation into Cu-rich and Fe-rich liquids occurred during rapid cooling. On the basis of the behavior of liquid-liquid phase separation of the Zr60Cu40-xFex system, the effect of partial substitution of Cu by Fe on the microstructure and phase formation of the Zr60Cu40-xFex alloys was investigated. The microstructure evolution and the competitive mechanism of phase formation in the as-quenched Zr60Cu40-xFex alloy were discussed. For the Zr60Cu20Fe20 alloy, liquid-liquid phase separation into Cu-rich and Fe-rich liquids and then liquid-glass transition occurred during rapid cooling and resulted in a heterogeneous structure with glassy Fe-rich matrix embedded with glassy Cu-rich nanoparticles. Considering this structure, the electrical properties and nanoindentation behavior of the as-quenched Zr60Cu20Fe20 alloy were examined. The abnormal change in electrical resistivity during crystallization and the effect of nanoscale phase separation on the shear transformation zone of the Zr60Cu20Fe20 alloy were analyzed.
