HIC
  • haprumine, mis on tingitud vesinikuaatomite kogunemisest ja vesinikumolekulide rekombinatsioonist (vt haprumine, vesinikhaprus, keskkonnavesinikhaprumine, sisemine vesinikhaprumine)
    Good to know
    • Vesinikhaprumine on omane suurtes toodetes ja kõrgtugevates terastes. Sageli on see vesiniku ebasoovitava lahustuvuse tagajärg metalli sulatamisel, kuumtöötlemisel, keevitamisel või galvaanimisel ja suurendab hapra (lõhestus)murdumise riski.
  • embrittlement or hydrogen-induced cracking in metals resulting from the presence of hydrogen atoms (see: embrittlement, environmental hydrogen embrittlement, internal hydrogen embrittlement, hydrogen britlleness)
    Good to know
    • Hydrogen embrittlement is distinctive in big workpieces and high-strehgth steels. It is often the result of unintentional of hydrogen into steel during melting, hot forming, welding or electroplaating and increases the risk of clevage fracture.
