Microstructure and misorientation profile analysis of grain boundary region in a cold rolled HfNbTaTiZr BCC-HEA, cold rolled until CR10%. (a) EBSD-IPF map showing crystallographic orientation parallel to the rolling direction (RD). (b) Misorientation profile among two grains G1 and G2 across a grain boundary, as shown in the inset of (a).
