Abstract Scope |
CuFeMnNi-based high entropy alloys were designed and optimized using CALculation of PHAse Diagrams (CALPHAD) approach. These high entropy alloys in as-cast condition exhibit good tensile properties. The homogenization process was selected based on calculated phase diagrams. Improvement on strength and ductility was achieved by cold rolling in combination of annealing at different temperature. Aluminum was added to enhance the mechanical properties of the base alloy through precipitation strengthening. The corrosion resistance of CuFeMnNi-based high entropy alloys can be improved by the addition of chromium. The strengthening mechanism in CuFeMnNi-based high entropy alloys was revealed using advanced electron microscopy techniques. |
