“…is result is consistent with the previous analysis result of undercooled Cu-Co melt [12]. However, in the later stage of liquid-phase separation, there is a slight deviation between the results in this study and previous results [2,12] because the maximum undercooling achieved in the study is not large enough.…”

“…Figure 2 illustrates the measured cooling pro les of three Cu-15 wt.% Fe samples at di erent undercooling states. On the curve (a), there was a recalescence corresponding to the growth of primary c-Fe dendrites (at about 1543 K) and then led to thermal arrest, which determined the liquidus temperature, T L ≈ 1578 K. e measured T L was consistent with the value in the equilibrium phase diagram [2], thus con rming the present temperature calibration. Moreover, it is also con rmed in Figure 3, since c-Fe dendrites are clearly visible.…”

“…In the early stage of liquid-phase separation, the diffusion coefficient of drops of the L1 (Fe-rich) phase in the melt is large and the dynamic viscosity is very small due to the low temperature. As a result, the above three necessary conditions for the Ostwald ripening are obtained [2]. At the same time, a free migration and coagulation process do not occur due to the short interval ∆t with low undercooling.…”

“…e parameter k is defined in [19]. Combining (2) and (3), the diffusion coefficient is proportional to the temperature, and the dynamic viscosity is inversely proportional to the temperature. In the early stage of liquid-phase separation, the diffusion coefficient of drops of the L1 (Fe-rich) phase in the melt is large and the dynamic viscosity is very small due to the low temperature.…”

“…When the melt cools rapidly, the liquid-phase separation occurs, thus leading to solidification below the liquid metastable miscibility gap. e liquid-phase separation of Cu-Fe alloy has been experimentally investigated at home and abroad, and the existence of liquid metastable miscibility gap has been proved [2,3].…”

e solidification microstructure evolution of undercooled Cu-15 wt.% Fe alloy melt was studied in this study by the combined method of glass fluxing and overheating. e liquidus and peritectic reaction temperatures of Cu-15 wt.% Fe were experimentally obtained, and the obtained results were consistent with the previous studies. Based on the experimental results and related theories, the solidification process and microstructure evolution of undercooled Cu-15 wt.% Fe alloy melt were illustrated. e conclusions provide the basis to the further study on the liquid-phase separation and application of copper-iron alloy.
