Sangano repasi-kabhoni simbi pakamuri tembiricha deformation of ferrite uye pearlite, kana pane bhendi chimiro ferrite uye pearlite alternating mitsetse sangano.Yakaderera kabhoni simbi isina musono pombi bhendi chimiro, kubva mukamuri tembiricha kusvika kune yakajairika tembiricha, kana kuburikidza neAc1 tembiricha, shanduko yeeutectoid inoitika, pearlite shanduko ye austenite.Muchiitiko ichi, izvo zvikamu hazvisi homogeneous austenite, nekushisa kwekushisa kunodarika Ac3, ferrite yakasimba mhinduro inopedzwa, ipapo chimiro chesimbi chinoshandurwa kuita imwe-phase austenite, sezvo tembiricha inoramba ichiwedzera uye normalizing tembiricha incubation, iyo austenite zvachose yunifomu.

Yakaburitswa kubva kune yakajairika tembiricha kutonhora Mushure me incubation, apo kutonhora kwesimbi kubvisa yakakura bhendi chimiro neyakaomesesa kutonhora mwero (kureva, kudzvinyirira ferrite inonaya kubva kune austenite kutonhora mwero), iyo simbi pombi eutectoid ferrite muviri inodzvanywa, kuitira kuti ferrite haina precipitate uye kubvisa solvent inoramba ari austenite, uye sezvo tembiricha inoderera nokuwedzera dhigirii supercooling, uye hazvizoitiki zvakare precipitated pro-eutectoid ferrite, kubudikidza zvakananga supercooled austenite decomposition chigadzirwa kupinda eutectoid ferrite + cementite, asi kusiyana eutectoid simbi yakagadzirwa, inonzi "pseudo-eutectoid" nokuti "pseudo-eutectoid" hapana eutectoid ferrite kuvapo kwemuviri, saka microstructure yesimbi yakasungirirwa chimiro haipo.Kuiswa kwepombi kubva pakubikwa mushure mekudzikamisa tembiricha, mwero wekutonhora wakaderera pane bhendi chimiro chesimbi kubvisa yakakosha kutonhora mwero wekunonoka kutonhora, kana tembiricha yadzikiswa kuita Ac3, yekutanga yakapera kabhoni simbi austenitic ferritic precipitation zone pamberi ( Iyo kabhoni. -yakashata nharaunda yemubereki chikamu nezve bhendi chimiro), nekuderera kunonoka kutonhora uye tembiricha eutectoid ferrite vhoriyamu inowedzerwa zvishoma nezvishoma kusvika kutonhora kusvika kuAc1 kana austenite ichipinda pearlite, pakamuri tembiricha Iyo microstructure yesimbi, yakaonekwa ferrite uye pearlite mabhendi. vakabata sangano rimwe chete.
