The present work systematically studied nonequilibrium solidification microstructure and its morphology evolution with undercooling of Cu60Ni40 binary alloy and Cu60Ni35Co5 ternary alloy, and the characteristic undercooling degree of alloy evolution was determined. Combining with BCT model, dendritic growth of undercooled Cu–Ni alloy was studied. On the basis of the above, a new ternary single-phase alloy was formed by adding minor Co element into Cu60Ni40 alloy. Subsequently, a comparative analysis was conducted on Cu60Ni40 and Cu60Ni35Co5 alloys, exploring the effect of Co element on the evolution of microstructure of deeply undercooled Cu–Ni alloys.
