摘要：
Copper-based monotectic alloys (Cu-Co, Cu-Fe, Cu-Cr, etc.) have received extensive attention from scholars in the field of materials science at home and abroad due to their excellent electrical, magnetic and mechanical properties. During the preparation process, copper-based monotectic alloys were referred to as immiscible alloys due to the occurrence of liquid phase separation leading to severe segregation structures. Past research primarily focused on seeking preparation methods to achieve uniform microstructure in copper-based monotectic alloys. However, recent studies have shown that strength-ductility synergy of the heterogeneous structures of segregated microstructures enhances the toughness of the material, offering a new direction for the further development of copper-based monotectic alloys. In this paper, the theoretical research results on the formation mechanism of liquid phase separation and segregation structure of copper-based monotectic alloys at home and abroad (including the evolution of liquid phase separation structure, the thermodynamics of liquid phase separation and the nucleation and growth kinetics of second phase droplets) were reviewed. The current mainstream methods for improving segregation structure (including micro-alloying method, rapid solidification method and laser forming method) were summarized. The strength-ductility synergy of the two-phase composite microstructure of copper-based monotectic alloys due to liquid phase separation characteristics was described. Finally, the future research and development direction of copper-based monotectic alloys was prospected. © 2024 Central South University of Technology. All rights reserved.
