“…The thermodynamic investigations of liquid Cu-based alloys and their solidification characteristics are of significance for understanding their physical and chemical properties [7][8][9][10][11][12]. Therefore, many efforts have been made to explore these subjects in recent years [13][14][15][16].…”

In this work, a CuCe alloy was prepared using a directional solidification method at a series of withdrawal rates of 100, 25, 10, 8, and 5 μm/s. We found that the primary phase microstructure transforms from cellular crystals to cellular peritectic coupled growth and eventually, changes into dendrites as the withdrawal rate increases. The phase constituents in the directionally solidified samples were confirmed to be Cu2Ce, CuCe, and CuCe + Ce eutectics. The primary dendrite spacing was significantly refined with an increasing withdrawal rate, resulting in higher compressive strength and strain. Moreover, the cellular peritectic coupled growth at 10 μm/s further strengthened the alloy, with its compressive property reaching the maximum value of 266 MPa. Directional solidification was proven to be an impactful method to enhance the mechanical properties and produce well-aligned in situ composites in peritectic systems.

“…Cu-Ni system is characterized by unlimited solubility of components, both in solid and liquid state [12], the same can be said about Ce-La system [13]. According to the phase diagram of the Cu-Ce [14], the system has five compounds: Cu 6 Ce, Cu 5 Ce, Cu 4 Ce, Cu 2 Ce, CuCe, where only Cu 6 Ce and Cu 2 Ce are congruently melted. It should be noted that the solubility of cerium in solid copper according to [15] is only 0.2 wt.…”

An experimental study of the phase composition for nine samples of the Cu–Ni–Ce–La alloys with different content of components was carried out. The nickel concentration in the experimental samples varies from 3 to 40 wt. %, the sum of cerium and lanthanum concentrations was not exceed 7 wt. %. Alloys samples of the system Cu–Ni–Ce–La were studied using scanning electron microscopy and microprobe analysis, as well as X-ray analysis. Also, Vickers micro hardness was measured on the cross sections of the experimental samples. In this work, the conditions of intermetallic compounds formation in the as-cast samples were studied. The results of the work can be used for the technological processes analysis of copper and copper-based alloys production.
