Peri-eutectic solidification and complicated microstructural evolution of liquid undercooled Cu-Ag-Sb alloy

►Rapid solidification of Cu-Ag-Sb alloy under two conditions was realized. ► We emphasized on microstructural evolution and solidification pathways. ► Two types of peri-eutectic transition take place during solidification. ► The peri-eutectic transition mechanisms were proposed correspondingly.
