Kupanga pambuyokutentha mankhwala azokopa zazikulupambuyokupangakupanga, mwamsanga pambuyo mankhwala kutentha amatchedwapost-kulembakutentha mankhwala.Cholinga chapost-kulembakutentha mankhwala a forgings lalikulu makamaka de-stress, recrystallize chimanga kuyenga ndi dehydrogenation nthawi yomweyo.
1. Recrystallization mankhwala Pambuyo angapo recrystallization mankhwala a forgings lalikulu, tirigu kuyenga, microstructure kusintha, ntchito bwino.
2. Dehydrogen annealing adzachepetsa haidrojeni mukupangas mpaka malire hydrogen zili pansipa, ndi kupanga kugawa yunifolomu, pofuna kupewa ngozi ya mawanga woyera, wa hydrogen embrittlement.

Kusungunuka ndi kufalikira kwa hydrogen mu gawo 7 ndi gawo A ndizosiyana, makamaka kusungunuka kochepa komanso kufalikira kwakukulu kwa haidrojeni mu gawo A, zomwe zimapangitsa kuti haidrojeni azifalikira kunja nthawi zonse.Dehydrogenation annealing nthawi zambiri imaphatikizidwa ndi recrystallization.Kutentha kwa dehydrogen annealing nthawi zambiri kumakhala 650 ℃.Pambuyo pa annealing, iyenera kuziziritsidwa pang'onopang'ono kuti muteteze kupsyinjika kwatsopano kwa mkati.Kuziziritsa kwakukulu kumagawidwa m'magawo awiri: pamwamba pa 400 ℃, chifukwa cha pulasitiki yabwino yachitsulo, kupanikizika kwamkati sikuli kophweka, kotero kuzirala kungakhale kofulumira;Pansi pa 400 ℃, kuzizira kumachepa.Kwa forgings ndi zinthu zambiri aloyi ndi zofunika ntchito apamwamba, mmodzi kapena angapo recrystallization kutentha mankhwala chofunika pambuyo panga, kuti patsogolo dongosolo ndi ntchito forgings.
