| Abstract | |
In this study, the semisolid deformability and processability of three CoCrCuxFeNi 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. (AU) | |
