The hydrogen embrittlement behavior of CoCrFeNi high-entropy alloy (HEA) fabricated by laser-powder bed fusion (L-PBF) under ex-situ and in-situ hydrogen charging conditions was investigated. The ex-situ hydrogen pre-charged sample showed excellent resistance to hydrogen embrittlement, whereas in-si...
