Ikimenyetso cyibanze cya hydrogène cyatewe no kuvunika gutinda ni ukuvunika 'gusukuye' kuvunika kugaragara nyuma yamasaha cyangwa iminsi nyuma yimpeshyi yashizwemo igashyirwa munsi yumutwaro, nubwo bidatinze kunanirwa guterana. Ubuso bwavunitse mubisanzwe bwerekana gucikamo ibice munsi ya Scanning Electron Microscope (SEM). Ibi biterwa na atome ya hydrogène yimukira mu turere twinshi twinshi (impinga yumuraba). Kugira ngo wirinde ibi, isoko igomba gutekwa $ 190 ^ {\ umuzenguruko} C \ pm 10 ^ {\ umuzenguruko} C $ mu masaha 1-4 uhereye igihe washyizeho kugirango wirukane hydrogen ikwirakwijwe. Kunanirwa guteka bidatinze bituma hydrogène ifata kumupaka wimbuto, biganisha kuri embrittlement.
