Given That, hydrogen embrittlement, happens while in the atomic condition of hydrogen, as a result our obtaining while in the atomic interaction of hydrogen with NbC, VC, TiC, and MnS confirmed which the toughness from the trapping on the hydrogen atom could be categorized as: TiC+H>VC+H>NbC+H> MnS+H.
