DHDZ: Waa maxay hababka tirtiridda been-abuurka?

Habka tirtiridda eebeen abuurashowaxaa loo qaybin karaa nusqaamin dhamaystiran, kabuubin aan dhamaystirnayn, xinjiro xinjir ah, xinjirta faafinta (homogenizing annealing), annealing isothermal, ka saarista diiqada iyo dib-u-celinta recrystallization iyadoo loo eegayo halabuurka, shuruudaha iyo ujeedada ka-saarista.
(1) dhamaystirka habka tirtiridda
①Baaxadda codsiga:Birta kaarboon dhexdhexaadka ah, shubida birta kaarboonka dhexdhexaadka ah, qaybo alxanka ah,been abuurasho, qaybaha duuban iyo daawaynta kale ee nuugista.
② Si buuxda loo tirtiray B
A. Hagaajinta qaab dhismeedka hadhuudhka, nadiifi cabbirka hadhuudhka, baabi'inta qaab dhismeedka Widmannian iyo qaab-dhismeedka xidhxidhan;
B. Iska yaree adkaanta oo wanaaji waxqabadka goynta;
C. Ka saar walaaca gudaha;
D. Daaweynta kulaylka kama dambaysta ah ee qaybaha aan muhiimka ahayn.

(2) Habka nuugista oo aan dhammaystirnayn
①Baaxadda codsiga:daawaynta annealing ee birta hypoeutectoid, birta qaab dhismeedka carbon, carbon cable qalab steel, birta qaab dhismeedka alloy hoose, birta alloy hoose iyo forgings birta hyeutectoid, qaybo kulul duudduuban, iwm.
②Ujeedada kaabista aan dhamaystirnayn:si loo baabi'iyo walbahaarka gudaha ee is-rog-rog-rogid, la yareeyo adkaanta iyo hagaajinta adkaanta.

(3) xinjirowga dhiigga
①Baaxadda codsiga:
A. Diyaarinta iyo daaweynta kulaylka ee birta xajinta iyo qalabka iyo birta kale ee hypereutectoid;
B. Qallafsanaanta qabow ee daawaynta baabiinta birta kaarboon dhexdhexaad iyo hoose iyo dhexdhexaad iyo hoose
②Ujeedada dabar goynta spheroidizing:
A. Waayobeen abuurashou baahan in la gooyo, la yareeyo adkaanta iyo hagaajinta waxqabadka goynta;
B. Si loo hagaajiyo caagga ah ee workpiece qabow-deformed iyada oo aan la gooyn;
C. Kaarbiid wareegsan si looga hortago kulaylka daminta dambe iyo in loo diyaargaroobo aaska ugu dambeeya ee kulul;
D. Ka saar walaaca gudaha.
(4) Annealing Isothermal
①Codsiga xinjirowga isothermal:dhinta birta, alwaax birta forgings, qaybaha shaabadeynta.
②Faa'iidooyinka xinjirowga isothermal:waxay soo gaabin kartaa wareegga soo saarista waxayna yareyn kartaa kharashka wax soo saarka.
