Bungwe la otsika mpweya zitsulo firiji mapindikidwe ferrite ndi pearlite, ngati pali gulu dongosolo la ferrite ndi pearlite alternating mikwingwirima gulu.Kapangidwe ka band kachitsulo kakang'ono kachitsulo kopanda mpweya, kuchokera kuchipinda kutentha kupita ku kutentha kwanthawi zonse, pomwe kutentha kwa Ac1, kusintha kwa eutectoid kumachitika, kusintha kwa pearlite kwa austenite.Pankhaniyi, zigawo zikuluzikulu si homogeneous austenite, ndi Kutentha kutentha kuposa Ac3, ferrite olimba njira yatha, ndiye dongosolo la zitsulo n'kukhala limodzi gawo austenite, monga kutentha akupitiriza kuwonjezeka ndi normalizing kutentha makulitsidwe, ndi austenite kwathunthu yunifolomu.

Anamasulidwa ku normalizing kutentha kuzirala Pambuyo makulitsidwe, pamene kuzirala mlingo wa zitsulo kuthetsa lalikulu banded dongosolo ndi yovuta kuzirala mlingo (ie, kupondereza ferrite precipitate ku mlingo kuzirala austenite), ndi chitsulo chitoliro eutectoid ferrite thupi ndi kuponderezedwa, kotero kuti ferrite si precipitate ndi kuchotsa zosungunulira zotsalira mu austenite, ndi kutentha amachepetsa poonjezera mlingo wa supercooling, ndipo sizidzachitikanso mpweya ovomereza-eutectoid ferrite, mwachindunji supercooled austenite kuvunda mankhwala mu eutectoid ferrite + cementite, koma mosiyana eutectoid zitsulo zikuchokera, wotchedwa "pseudo-eutectoid" chifukwa "pseudo-eutectoid" palibe eutectoid ferrite kukhalapo kwa thupi, kotero microstructure wa zitsulo banded dongosolo kulibe.Kusungunula kwa chitoliro kuchokera ku zophikidwa pambuyo pa kutentha kwanthawi zonse, kuzizira kumakhala kochepa poyerekeza ndi gulu lachitsulo kuti athetse kuzizira kwapang'onopang'ono, pamene kutentha kumatsitsidwa kukhala Ac3, choyamba chatha carbon steel austenitic ferritic precipitation zone patsogolo ( The carbon -Kusauka kwa gawo la gawo la kholo la kapangidwe ka bandi), ndikuchepetsa kuziziritsa pang'onopang'ono ndi kutentha kwa eutectoid ferrite voliyumu kumakulitsidwa pang'onopang'ono mpaka kuzizira kwa Ac1 pamene austenite kukhala pearlite, kutentha kwapakati The microstructure yachitsulo, idawoneka ferrite ndi pearlite band. anamanga bungwe lomwelo.
