Figure 9. Nanoindentation analysis of the HS-HEA at 0%, 10%, and 30% plastic strain. (A-C) The ECC micrograph revealing the microstructure evolution; (D-F) Representative EBSD IPF images overlayed IQ maps showing nano-indents in both recrystallized (RX) and non-recrystallized (NRX) zones, respectively; (G-I) The distribution of nanoindentation hardness (H_n) in RX and NRX zones. $$ \overline{H_{n}} $$, average nanoindentation hardness. HS: Heterogeneous structure; HEA: high-entropy alloy; ECC: electron channeling contrast; EBSD: electron backscatter diffraction; IPF: inverse pole figure; IQ: image quality.
