In Fig. 6 (b, c), the CNB flake powder is cold-welded to form flake particles with layered structures after 6 + 1 h SSBM because the high speed of the planetary mill can cause the flake particles to stick to one another [27], [28]. The cold-welded CNB particles subjected to 2 + 1 h, 4 + 1 h, and 8 + 1 h SSBM show similar morphology.
