Usayizi wokusanhlamvu ubhekisela kusayizi wokusanhlamvu ngaphakathi kwekristalu kasayizi wokusanhlamvu. Ubukhulu bokusanhlamvu bungavezwa ngendawo evamile noma ububanzi obuphakathi bokusanhlamvu. Usayizi wokusanhlamvu uvezwa yizinga likasayizi wokusanhlamvu ekukhiqizeni kwezimboni. Usayizi wokusanhlamvu ojwayelekile mkhulu, okungukuthi, ucolile ungcono. Ngokusho kwesihloko esilandelayo, ngithemba ukuthi ingakusiza ukuba uqonde usayizi wokusanhlamvu we-forgings. Ngikholelwa ukuthi bajwayele usayizi wokusanhlamvu we-forging, ngakho-ke akumele sazi okuningi ngosayizi wokusanhlamvu we-forging.
I-deformation yepulasitiki ye-forging iphula amakristalu e-dendritic eyinhloko futhi inomphumela obalulekile wokuhluzwa okusanhlamvu. Ngakolunye uhlangothi, kukhona inqubo yokuvuselela kabusha ngesikhathi sokuguqulwa kwepulasitiki ekushiseni okuphezulu. Ngesikhathi high lokushisa plastic deformation, usayizi okusanhlamvu weama-forgingsemva recrystallization kunqunywa izinga lokushisa, deformation degree kanye nesivinini. Ngakho-ke, usayizi wokusanhlamvu weama-forgingsetholwe ngezinqubo ezahlukene zokubumba ihlukile.

Izakhiwo eziyinhloko zemishini ye-forging enezinhlamvu eziqinile ukuthi ipulasitiki yabo nokuqina kuphansi kakhulu kunalezo ezinezinhlamvu ezinhle. Ukucwenga okusanhlamvu ngokwelashwa okushisa akuwona nje kuphela umsebenzi onzima futhi obizayo, kodwa futhi kunzima kakhulu futhi akunakwenzeka kwezinye izinsimbi ze-alloy. Ngakho-ke, okunengqondoukuqambainqubo yamabanga athile ensimbi kufanele isetshenzwe ngokusho komdwebo we-recrystallization wokusebenza okushisayo.
Ukuphakama kwezinga lokushisa lokubumba, likhulu usayizi wokusanhlamvu we-forging ngemva kokwenziwa kabusha kwekristalu. Ngakho-ke, izinga lokushisa lokugcina lokubumba kufanele lincishiswe ngangokunokwenzeka ukuze kuqinisekiswe ukucolisiswa okusanhlamvu ngaphansi kwesimo sokuthi ama-forging angeke akhiqize ukushisa okuphansi kokukhwabanisa kokuqhekeka. Kodwa-ke, kunzima kakhulu kuma-forgings amakhulu ukuqinisekisa izinga lokushisa elifanayo lokugcina eliphansi eliphansi kuzo zonke izingxenye ze-forging efanayo. Lokhu kungenziwa kuphela ngolwazi nekhono lezisebenzi eziyizingcweti.
Kwesinye isikhathiukuqambaizinga lokushisa, kukhona ibanga elibalulekile le-deformation degree. Uma idigri ye-deformation ingaphakathi kwalolu bubanzi, uhlamvu oluphinde lwahlanganiswa lwe-fama-orgingsumaholoholo uma kuqhathaniswa. Ngakho-ke, izinga lokuguqulwa ngesikhathi sokubumba, ikakhulukazi emlilweni wokugcina, kufanele kugwenywe ngangokunokwenzeka ngaphakathi kwezinga elibucayi lokuguqulwa.
Okusanhlamvu akuyona iyunifomu ibhekisela kwezinye izingxenye zokusanhlamvu okukhangayo ikakhulukazi, ezinye izingxenye ezincane. Isizathu esiyinhloko sobukhulu bokusanhlamvu obungalingani ukuthi ukuguqulwa okungalingani kwe-billet kwenza idigri yokuhlukaniswa okusanhlamvu ihluke, noma i-deformation degree yendawo yendawo iwela endaweni ebucayi yokuguqulwa, noma ukuqina komsebenzi wendawo we-superalloy, noma indawo yendawo. usayizi wokusanhlamvu omahhadla uma ucisha futhi ufudumala. Izinsimbi ezikwazi ukumelana nokushisa kanye nama-superalloy azwela kakhulu ekungangeni kokusanhlamvu okusanhlamvu. Usayizi wokusanhlamvu ongalingani uzonciphisa ukuqina nokusebenza kokukhathala kwama-forging.
Lesi sihloko sikhuluma ikakhulukazi ngosayizi wokusanhlamvu we-forgings. Ngethemba ukuthi kuzoba usizo kuwe.
