摘要：

Three kinds of experimental methods for different cooling rates can lead to a different degree of supercooling Cu50Co50 alloy. The data were obtained by differential scanning calorimetry and were compared with the calculated phase diagrams. The microstructure of Cu50Co50 shows that the faster the cooling speed, the greater the supercooling will be, which means the alloy composition is relatively uniform and the droplets of Co-rich are not gathered obviously. With the decrease of the cooling speed, the droplets of Co-rich dispersed in Cu matrix have enough time to finish nucleate forming. In the cooling speed of the slowest samples, parts of the organization formed Co-rich dendrites distributed in the matrix. Our work discusses the relationship between the microstructure and L-L phase separation in undercooled liquid of Cu50Co50.
