Microstructural evolution of HfNbTaTiZr BCC-HEA during cold rolling for various strain intervals. (a) CR5%, (b) CR10% and (c) CR35%. (a-c) EBSD image quality (IQ) map showing low- and high-angle grain boundaries (L/H-AGB). LAGBs with misorientation (θ), 3° ≤ θ < 15° are shown in red, while HAGBs with θ ≥ 15° are shown in blue lines. (a′-c′) High magnification area specific BSE/ECCI images of the corresponding microstructures shown in (a-c).
