Dildilaaca qabowSababaha: qofka lagu samaynayo alxanka marka xoog weyni si fudud loo jeexjeexi karo habka qaboojinta adkeynta walxaha alxanka; alxanka heerka qaboojinta aad bay u daahday in laga baxsado hadhaaga hydrogen ee alxanka, atom hydrogen ah oo ku xidhan molecules hydrogen si xaalad gaseous galay daloolada ganaaxa ee birta oo keena cadaadis badan, si ay birta qabow-samaysan ee maxalliga ah dildilaaca. cadaadis badan; alxanka walaaca iyo falanqaynta cidhiidhiga kacsan oo diiradda saaraya hydrogen ebrittlement iyo qallafsanaan dhacaan isku mar si fudud in la sameeyo marka qabow dillaaco.

Tallaabooyinka ka hortagga: kulaylka ka hor iyo qaboojinta tartiib tartiib ah ka dib alxanka, kuleylku saameeyay aagga austenite wuxuu noqon karaa heerkul ku filan, si looga fogaado unugyada adag, iyadoo la yareynayo doorka diiqada alxanka; hypothermia waqti ka dib alxanka annealing, dehydroepiandrosterone daawaynta, baabi'inta stress ka dhasha alxanka, iyo in ay faafin ee hydrogen in hab waqti ku haboon dibadda si ay u tagaan; xulashada korantada nooca hydrogen ah oo hooseeya iyo qulqulka alkaline ama austenitic silig birta alxanka ah, iwm., alaabooyinka loo baahan yahay qalajin iyo jeexdin nadiif ah oo adag; ilaalinta iyo xoojinta alxanka alxanka ah ee nadiifinta dusha sare, si looga fogaado faragelinta hydrogen; dooro tilmaamo alxanka oo macquul ah, adigoo isticmaalaya isku imaatinka macquulka ah iyo isku xigxiga alxanka.
