Bayan-kirkirezafi magani namanyan ƙirƙirabayanƙirƙirakafa, nan da nan bayan ana kiran maganin zafibayan jabuzafi magani. Manufarbayan jabuzafi magani na manyan forgings ne yafi de-stress, recrystallize hatsi tacewa da dehydrogenation a lokaci guda.
1. Recrystallization magani Bayan da yawa recrystallization jiyya na manyan forgings, hatsi tacewa, microstructure inganta, aikin inganta.
2. Dehydrogen annealing zai rage hydrogen a cikinƙirƙiras zuwa iyaka hydrogen abun ciki a kasa, da kuma sanya ta rarraba uniform, domin kauce wa hadarin farin spots, hydrogen embrittlement.

Solubility da rarrabawa na hydrogen a cikin lokaci na 7 da lokaci A sun bambanta, musamman ƙarancin solubility da babban adadin adadin hydrogen a cikin lokaci A, wanda ke sa hydrogen ya ci gaba da yaduwa a waje yayin aikin cirewa. Sau da yawa ana haɗewar cirewar ruwa tare da recrystallization. Yawan zafin jiki na dehydrogen annealing yawanci 650 ℃. Bayan annealing, ya kamata a sanyaya a hankali a hankali don hana sabon damuwa na ciki. Janar sanyaya ya kasu kashi biyu matakai: sama da 400 ℃, saboda da kyau plasticity na karfe, ciki danniya ba sauki kafa, don haka sanyaya iya zama sauri; A kasa 400 ℃, da sanyaya kudi zai rage gudu. Don ƙirƙira tare da ƙarin abubuwan gami da buƙatun aiki mafi girma, ana buƙatar ɗaya ko ma mahara recrystallization zafi magani bayan ƙirƙira, domin inganta tsari da kuma yi na forgings.
