Mokhoa oa ho laola deformation ea forgings nakong ea phekolo ea mocheso
Li-forging tse ling li hloka kalafo ea mocheso ka mor’a ho futhumatsa le ho forging. Nakong ea phekolo ea mocheso, ela hloko ho fokotsa tsela le palo ea likarolo tse behiloeng. E ‘ngoe ke ho fanyeha holimo ka hohle kamoo ho ka khonehang. Sebaka se pakeng tsa karolo ea boraro le kotara ea bolelele bo feletseng, ‘me ea bone e robala holim’a lisebelisoa tsa tšepe tse sa keneleng mocheso. Ho beoa ho sa nepahalang ke le leng la mabaka a etsang hore deformation e be teng.
Taba ea bobeli, mofuta oa ho pholisa le ho tima mocheso kalafong ea mocheso, ts’ebetso ea pholileng, ha ho khetho kapa ts’ebetso e sa lokelang e tla amahanngoa le deformation e thata. Phetoho ea ts’ebetso ea pholileng e ka fetoloa ka ho fetola viscosity, mocheso, khatello ea metsi holim’a metsi, ho sebelisa li-additives, ho hlohlelletsa, joalo-joalo Ho phahama ha viscosity ea oli e timang le mocheso o phahameng, ho fokotseha ha elliptical deformation. Sebakeng sa phomolo, deformation e nyane.
Ho phaella moo, ela hloko matla a ho fetola mocheso oa ho tima nakong ea phekolo ea mocheso. Mocheso oa ho tima ke oli-o pholileng ho mocheso o phahameng hanyenyane ho feta ntlha ea Ms, ebe ka potlako le ho bolokoa sepakapakeng ho etsa mocheso o akaretsang oa karolo ea seaparo, ebe o pholile ka oli ho etsa junifomo ea phetoho ea martensitic. Ho se tloaelehe ha deformation ho ntlafetse haholo.
