Enhancing plasticity in high-entropy refractory ceramics via tailoring valence electron concentration

Bottom-up design of high-entropy ceramics is a promising approach for realizing materials with unique combination of high hardness and fracture-resistance at elevated temperature. This work offers a simple yet fundamental design criterion – valence electron concentration (VEC) ⪆9.5 e-/formula unit t...
