Abstract:
The properties and microstructure of (Cr, Fe, V)-(Ta, W) high-entropy films (HEFs) are studied using combinatorial strategies. The compositional library of (Cr0.33Fe0.33V0.33) x(Ta0.5W0.5)100- x, (0 < x < 100), HEFs are fabricated by cosputtering to discover potential photothermal conversion materials. By verifying points in the compositional library, the structure and property variation according to the atomic content of elements are carefully studied. Results indicate that the films exhibit an amorphous structure when x ranges from 86.9 to 32.5, and high concentrations of Ta and W lead to the formation of a BCC structure in the films. The solar absorptivity of the films peaks at the transitional area from an amorphous to BCC structure. Our research provides an efficient combinatorial technique to discover HEFs with high performance.
