Indlela yokuthintela ukuveliswa koxinzelelo lokucima ngexesha lokupholisa imodeli eqhelekileyo?

Ngoko ukuthintela njani ukuveliswa koxinzelelo lokucima ngexeshaisiseko sokungunda esichanekileyo esichanekileyoUkupholisa?
Ukupholisa kufuneka kusetyenziswe ukuphelisa uxinzelelo, kwaye emva kokucinywa kweemodeli eziqhelekileyo, ubilise i-30 ~ 60min ngaphambi kokupholisa unyango, ukuphelisa i-15% ukuya kwi-25% yoxinzelelo lokucima, ukuzinzisa i-aus eseleyo, emva koko iqhutywe - 60 ° C unyango oluqhelekileyo lokupholisa okanye ingqele enzulu. unyango lwe -120 ° C.

Iqondo eliphantsi lobushushu, kokukhona intsalela ye-austenite inguqu linani le-martensite, kodwa akunakwenzeka ukuguqula. Iziphumo zovavanyo zibonisa ukuba i-austenite eshiyekileyo ibalelwa malunga ne-2% ukuya kwi-5%, kunye nenani elincinci le-austenite elishiyekileyo lingenza uxinzelelo olucothayo kunye ne-buffer. Kuba intsalela ye-austenite ithambile kwaye yomelele, inokufunxa ngokuyinxenye amandla okwanda okukhawulezileyo kokuqina, isuse uxinzelelo lotshintsho lwesigaba. Emva kokunyanga okubandayo, imodeli eqhelekileyo ithathwa emanzini atshisayo ukutshisa ukushisa, kwaye i-40% -60% yoxinzelelo lonyango olubandayo lunokupheliswa. Xa iqondo lobushushu linyuka ukuya kwiqondo lobushushu, kufuneka lincitshiswe kwangethuba ukuze kupheliswe ngakumbi uxinzelelo lonyango olubandayo, kunqande ukwenza iintanda zonyango olubandayo, ukufumana izicubu ezizinzileyo kunye nokusebenza, ukuqinisekisa ukubaisiseko sokungunda esichanekileyo esichanekileyo azikhubazeki ngexesha lokugcinwa kunye nokusetyenziswa.
