In this study, the semisolid deformability and processability of three CoCrCu_xFeNi high-entropy alloys (x = 1, 2, and 3) were evaluated. At 1175 °C, the Cu content had a major influence on the semisolid deformation due to its control of the liquid fraction. The semisolid alloys displayed a typical pseudoplastic rheological behavior. Only the CoCrCu₃FeNi alloy filled the die completely during thixoforming. The Vickers hardness decreased with increasing Cu content due to the different hardness values of the constituent FCC phases. The compression test results showed that the thixoformed CoCrCu₃FeNi had good plasticity and a yield stress of 310 MPa. Thus, semisolid processing can be an alternative route for manufacturing components made of high-entropy alloys.

在这项研究中，评估了三种 CoCrCu _x FeNi 高熵合金（x = 1、2 和 3）的半固态变形性和可加工性。在 1175 °C 时，Cu 含量对半固态变形有很大影响，因为它控制了液态部分。半固态合金表现出典型的假塑性流变行为。只有 CoCrCu ₃ FeNi 合金在触变成型过程中完全填充模具。由于组成的 FCC 相的硬度值不同，维氏硬度随着 Cu 含量的增加而降低。压缩试验结果表明，触变成型的CoCrCu ₃ FeNi具有良好的塑性，屈服应力为310 MPa。因此，半固态加工可以成为制造由高熵合金制成的部件的替代途径。
