A cobalt-rich eutectic high-entropy alloy in the system Al–Co–Cr–Fe–Ni

By using the well-established CALPHAD methodology, a cobalt-rich eutectic high-entropy alloy is designed and made for the system Al–Co–Cr–Fe–Ni. Microstructural studies show that the designed alloy has a dual FCC/BCC phase structure and is composed of nanostructured lamellar-irregular regions. The mechanical properties of the alloy are investigated by compression test. The ultimate strength and the ductility of the alloy are measured to be 2150 MPa and 40%, respectively. The effect of Al concentration on the microstructure and mechanical properties of the alloy is investigated.
