Inkqubo yokunyanga ubushushu yombhobho wentsimbi engenamthungo yindlela ebalulekileyo yokuphucula iimpawu zayo zoomatshini, iimpawu zomzimba kunye nokumelana nokugqwala. Nazi iinkqubo ezininzi eziqhelekileyo zokunyanga ubushushu kwimibhobho yentsimbi engenamthungo:
Ukuqokelela
- Inkqubo: Ukufutha i-Annealing kubandakanya ukufudumezaumbhobho wentsimbi ongenamthungoukuya kubushushu obuthile, uyibambe kuloo bushushu kangangexesha elithile, uze uyipholise kancinci.
- Injongo: Injongo ephambili kukunciphisa ubulukhuni kunye nokuqhekeka ngelixa kwandisa ukuguquguquka kunye nokuqina. Ikwasusa uxinzelelo lwangaphakathi oluvela ngexesha lokwenziwa. Emva kokutsalwa, isakhiwo esincinci siba yinto efanayo ngakumbi, nto leyo eyenza kube lula ukucutshungulwa kunye nokusetyenziswa okulandelayo.
Ukulungisa izinto zibe zesiqhelo
- Inkqubo: Ukulungisa izinto ngendlela eqhelekileyo kubandakanya ukufudumeza umbhobho wentsimbi ongenamthungo ngaphezulu kwe-Ac3 (okanye i-Acm) ngama-30 ~ 50 °C, uwubambe kolu bushushu ixesha elithile, uze uwupholise emoyeni emva kokuwususa esitovini.
- Injongo: Ngokufana nokuqhoboshela, ukuqhoboshela kujolisa ekuphuculeni isakhiwo esincinci kunye neempawu zoomatshini zombhobho. Nangona kunjalo, imibhobho eqhelekileyo ibonisa ubulukhuni kunye namandla aphezulu kunye nezakhiwo ezincinci zengqolowa, nto leyo eyenza ukuba zifaneleke ukusetyenziswa ezifuna ukusebenza okuphezulu koomatshini.
Ukucima
- Inkqubo: Ukucima kuquka ukufudumeza umbhobho wentsimbi ongenamthungo ukuya kubushushu obungaphezulu kwe-Ac3 okanye i-Ac1, uwubambe kobu bushushu ixesha elithile, uze uwupholise ngokukhawuleza ukuya kubushushu begumbi ngesantya esikhawulezayo kunesantya sokupholisa esibalulekileyo.
- Injongo: Eyona njongo kukufezekisa isakhiwo se-martensitic, ngaloo ndlela kwandisa ubulukhuni namandla. Nangona kunjalo, iipayipi ezicinyiweyo zihlala zibuthathaka kwaye ziqhekeka, ngoko ke zihlala zifuna ukufudunyezwa emva koko.
Ukunciphisa
- Inkqubo: Ukufudumala kubandakanya ukuphinda kufudumale umbhobho wentsimbi ocinyiweyo ukuya kubushushu obungaphantsi kwe-Ac1, uwubambe kobu bushushu ixesha elithile, uze uwupholise ukuya kubushushu begumbi.
- Injongo: Eyona njongo iphambili kukunciphisa uxinzelelo olushiyekileyo, ukuzinzisa isakhiwo se-microstructure, ukunciphisa ubulukhuni kunye nokuqhekeka, kunye nokuphucula ukuguquguquka kunye nokuqina. Ngokuxhomekeke kubushushu bokufudumeza, ukufudumeza kunokwahlulwahlulwa kudidi lwe-tempering ephantsi, i-tempering ephakathi, kunye ne-tempering ephezulu.
Ezi nkqubo zonyango lobushushu zingasetyenziswa zodwa okanye zidityaniswe ukuze kufezekiswe ukusebenza kombhobho wentsimbi okufunekayo. Kwimveliso yokwenyani, inkqubo efanelekileyo yonyango lobushushu kufuneka ikhethwe ngokwendlela ethile yokusetyenziswa kunye neemfuno zombhobho wentsimbi ongenamthungo.
