Ho qhekella ka moraophekolo ea mocheso oamekgatlo e meholokamoraforgingho theha, hang ka mor'a hore phekolo ea mocheso e bitsoaho qhekella ka moraophekolo ea mocheso. Sepheo saho qhekella ka moraokalafo mocheso oa forgings khōlō haholo-holo ho de-stress, recrystallize lijo-thollo tlhoekiso le dehydrogenation ka nako e tšoanang.
1. Phekolo ea Recrystallization Ka mor'a phekolo e 'maloa ea recrystallization ea forgings e kholo, ntlafatso ea lijo-thollo, ntlafatso ea microstructure, ntlafatso ea ts'ebetso.
2. Dehydrogen annealing e tla fokotsa hydrogen hoforgings ho moedi dikahare haedrojene mona ka tlase, le ho etsa kabo junifomo, e le ho qoba kotsi ea matheba a masoeu, hydrogen embrittlement.
Ho qhibiliha le ho hasana ha haedrojene mokhahlelong oa 7 le oa A li fapane, haholo-holo ho qhibiliha ho tlaase le coefficient e kholo ea phallo ea haedrojene mokhahlelong oa A, e leng se etsang hore haedrojene e tsoele pele ho ata ka ntle nakong ea ts'ebetso ea annealing. Dehydrogenation annealing hangata e kopantsoe le recrystallization. Thempereichara ea dehydrogen annealing hangata ke 650 ℃. Ka mor'a hore annealing, e lokela ho pholile butle ka hohle kamoo ho ka khonehang ho thibela khatello e ncha ea ka hare. Pholiso e akaretsang e arotsoe ka mekhahlelo e 'meli: ka holimo ho 400 ℃, ka lebaka la polasetiki e ntle ea tšepe, khatello ea ka hare ha e bonolo ho theha, kahoo ho pholisa ho ka potlaka; Ka tlase ho 400 ℃, sekhahla sa ho pholisa se tla fokotseha. Bakeng sa forgings tse nang le likarolo tse ngata tsa alloy le litlhoko tse phahameng tsa ts'ebetso, phekolo e le 'ngoe kapa e mengata ea mocheso oa recrystallization e hlokahalang ka mor'a ho qhekella, e le ho ntlafatsa sebopeho le ts'ebetso ea forgings.
