Recent investigations indicate similarity in the deformation behaviour of FCC single-phase Cantor alloy and two-phase CoCuFeMnNi HEA with that of solid solutions. However, deformation behaviour over a wide range of temperature, strain rate, strain and grain size is unexplored. The viewpoint paper provides the present status of our understanding of flow kinetics including strain hardening behaviour of FCC HEAs and way forward for BCC and multi-phase HEAs.

This approach can provide advanced materials with unique properties, including high strength with sufficient ductility and fracture toughness and excellent corrosion and wear resistance for a wide range of temperatures due to the concentrated alloying that cannot be obtained by traditional microalloying based on a single principal element. In addition, the alloy design approach provides new alloy systems in astronomical numbers with variety of microstructural attributes that can yield different properties, and hence conventional trial and error experimental methods for alloy development are redundant. With the help of high throughput experiments along with efficient computational tools, and artificial intellige...
