Low-cost Al0.1CrCuFeMnNi high-entropy alloy (HEA) is developed, based on substituting expensive elements by Mn. The structure of Al0.1CrCuFeMnNi is studied by synchrotron x-ray diffraction at room temperature and neutron diffraction from 800 °C to molten temperature. The results shows there are three phases [face-centered cubic (FCC)-1, FCC-2, and body-centered cubic (BCC)] present from RT to 1,100 °C. At 1,200 °C, two phases (FCC-2 and BCC) are present. However, only BCC phase is existing at 1,300 °C. The Al0.1CrCuFeMnNi solidification paths are also calculated, using the Scheil thermodynamic model. In addition, the simulated fraction of each phase within the as-cast Al0.1CrCuFeMnNi alloy is indicated. Thus, the structure evolution of Al0.1CrCuFeMnNi during cooling is proposed, combining both experimental results and thermodynamic calculations.
