I-post-forgingunyango ubushushu yeiifolishi ezinkuluemvaukwenzaukubumba, ngokukhawuleza emva kokuba unyango lobushushu lubizwapost-forgingunyango lobushushu. Injongo yepost-forgingunyango ubushushu forgings ezinkulu ikakhulu de-uxinzelelo, recrystallize ukucokisa iinkozo kunye dehydrogenation ngaxeshanye.
1. Unyango lwe-recrystallization Emva konyango oluninzi lwe-recrystallization ye-forgings enkulu, ukulungiswa kwengqolowa, ukuphuculwa kwe-microstructure, ukuphuculwa komsebenzi.
2. I-Dehydrogen annealing iya kunciphisa i-hydrogen kwi-ukwenzas ukuya umda isiqulatho hydrogen ngezantsi, kwaye wenze iyunifomu yokusasazwa kwayo, ukuze kuphetshwe ingozi amabala amhlophe, embrittlement hydrogen.
I-solubility kunye ne-diffusion coefficient ye-hydrogen kwisigaba sesi-7 kunye nesigaba A zahlukile, ngakumbi ukunyibilika okuphantsi kunye ne-coefficient enkulu yokusasazwa kwe-hydrogen kwisigaba A, esenza ukuba i-hydrogen iqhubeke isasazeka ngaphandle ngexesha lenkqubo yokucoca. I-Dehydrogenation annealing idla ngokudityaniswa kunye ne-recrystallization. Ubushushu be-dehydrogen annealing buqhele ukuba yi-650℃. Emva kokufakwa kwe-anneal, kufuneka ipholiswe kancinane kangangoko ukuthintela uxinzelelo olutsha lwangaphakathi. Ukupholisa ngokubanzi kwahlula ngamanqanaba amabini: ngaphezu kwe-400 ℃, ngenxa yeplastiki enhle yensimbi, uxinzelelo lwangaphakathi alulula ukwenza, ngoko ukupholisa kunokukhawuleza; Ngaphantsi kwe-400℃, izinga lokupholisa lizakucotha. Kuba forgings kunye nezinto ezininzi ingxubevange kunye neemfuno zokusebenza eziphezulu, enye okanye nokuba recrystallization ezininzi unyango ubushushu efunekayo emva forging, ukuze kuphuculwe isakhiwo kunye nokusebenza forgings.
