Been abuurashoka dib markii la demiyo, martensite iyo austenite la hayo waa xasilloonayn, waxay leeyihiin isbedel ururka iskiis isbeddelka xasilloonida, sida kaarboonka supersaturated ee martensite si ay u soo dedejiso burburka austenite haraaga ah si kor loogu qaado isbeddelka, sida for tempering tempering waa urur aan dheellitirnayn. si loo miisaamo hab-socodka ururka, habkani wuxuu ku xidhan yahay guuritaanka atomiga iyo faafinta oggolaanshahan oo ay weheliso dhamaystirka Heerkulka dabku wuu sarreeyaa, xawaaraha faafinta degdega ah; Taas beddelkeeda, kororka heerkulka heerkulka, qaab-dhismeedka deminta ee foornada waxay mari doontaa isbeddello taxane ah. Marka loo eego xaaladda isbeddelka qaab-dhismeedka yar-yar, heerkulka guud ahaan waxaa loo qaybiyaa afar marxaladood: burburka martensite, burburka austenite haraaga, kobaca uruurinta carbide iyo recrystalization ferrite.
Marxaladda koowaad (200)
(1) been abuurashotempering martensite decompose under 80 heerkulka heerkulka, demi birta oo aan isbedel ururka Ming S, dhacdo ee kaarboon ee martensite oo kaliya qayb ahaan, oo aan bilaabmin in ay burburiso in 80-200 tempering, martensite bilaabay inuu dumiyo, soo dedejiso carbides aad u khiyaano badan, la yareeyo jajab ballaaran oo martensite ah oo ku jira foornada kaarboon ee marxaladdan, sababtoo ah heerkulka heerkulka hooseeya, martensitic roobabka kaliya qayb ka mid ah atamka carbon supersaturated, sidaas darteed weli waa kaarboon ku jira a - Fe supersaturated adag solutionThe roobka ee carbide aad u fiican si siman u qaybiya in matrix ee martensite. Qaab dhismeedka isku dhafan ee saturation hoose ee Martensite iyo carbide aad u fiican ayaa loo yaqaan 'Martensite tempered'.

(2)been abuurashoDabeecad marxaladda labaad (200-300), burburka austenite haraaga ah marka heerkulku kor u kacay 200-300, burburka martensite ayaa sii socday, laakiin isbeddelka ugu weyn ayaa ah burburka austenite haraaga ee burburka austenite haraaga ah iyada oo loo marayo ballaarinta atamka kaarboonka. si ay u sameeyaan qayb qayb ah, ka dibna u jajaban galay wajiga alfa iyo isku dhafka ah ee ururka carbide, kuwaas oo formation of adkaanta birta bainite si cad hoos uguma dhacayso heerkan
(3)Marxaladda saddexaad (250-400) beddelka carbide ee xajinta foornada waxay ku jirtaa kala duwanaanshahan heerkulka. Heerkulka sare awgeed, awoodda faafinta atomka kaarboon waa ka xoog badan tahay, awoodda faafinta ee dib u soo kabashada atamka birta sidoo kale, martensite waxay burburisaa kala-guurka carbides roobabka iyo burburka austenite haraaga ah ayaa loo rogi doonaa sibidh xasilloon oo leh kala-soocid iyo beddelaad carbides, hoos u dhaca ee martensite ee jajabka kaarboonka cufka, qallooca martensite lattice wuu baaba'aa, isbeddelka martensite ee ferrite, hel qaybinta matrix ferritic gudaha sibidhka yar yar ama lamellar cementite ee ururka, ururka loo yaqaan tempering asal ahaan wuxuu meesha ka saaray marxaladan austenite deminta stress, engegnaanti, caag adag ayaa la hagaajiyay.

(4)Marxaladda afraad ee xamaasad been abuur ah (& GT; 400) koray carbide soo ururiyey iyo recrystallization of ferrite ay sabab u tahay heerkulka tempering waa mid aad u sarreeya, carbon iyo atamka birta leeyihiin awood xoog leh ee faafinta, samaynta wajiga saddexaad ee flakes cementite si joogto ah doonaa spheroidizing iyo koray. In ka badan 500-600, alfa recrystallization ayaa si tartiib tartiib ah u dhacda, luminaya qaab-dhismeedka ferrite ee saxanka asalka ah ama xaashida, iyo samee qaybinta hadhuudhka geeso geesaha ah ee ururka sida carbides granular matrix ferritic ah, kooxda loo yaqaan tempering sorbite xanaaqsan sorbite oo leh sifooyin farsamo oo dhamaystiran oo wanaagsan ee wajiga iyo qalloocinta shalash waxay baabi'isaa walbahaarka gudaha.
