1. I-ferrite
I-Ferrite iyisisombululo esiqinile se-interstitial esakhiwe yikhabhoni encibilike ku- -Fe. Ivamise ukuvezwa ngokuthi noma i-F.Igcina uhlaka lwe-cubic lattice olugxile ngobuningi lwe-alpha -Fe.Ferrite inokuqukethwe kwekhabhoni ephansi, futhi izakhiwo zayo zomshini zisondelene nalezo zensimbi emsulwa, ipulasitiki ephezulu kanye nokuqina, namandla aphansi nobulukhuni.
2. I-austenite
I-Austenite iyisisombululo esiqinile se-interstitial sekhabhoni encibilike ku-Fe, ngokuvamile evezwa njenge-A. , amandla aphansi, ubulukhuni obuphansi kanye ne-plastic deformation elula.

3. Usimende
I-Cementite iyinhlanganisela eyenziwe nge-iron ne-carbon, ifomula yayo yamakhemikhali i-Fe3C.Iqukethe i-6.69% ye-carbon futhi inesakhiwo se-crystal esiyinkimbinkimbi.I-cementite inobunzima obuphakeme kakhulu, i-plasticity empofu, cishe i-zero, futhi iyisigaba esinzima nesiphukayo. I-Cementite idlala indima yokuqinisa i-carbon steel.Ema-alloys e-iron-carbon, lapho i-carbon content iphezulu, i-cementite iyanda, ubulukhuni buyanda futhi i-plasticity ye-plasticity iyancipha. ama-alloys.
4. I-Pearlite
I-Pearlite ingxube yemishini ye-ferrite ne-cementite, evame ukuchazwa yi-P. Isilinganiso sekhabhoni ye-pearlite singu-0.77%, futhi izakhiwo zayo zomshini ziphakathi kwe-ferrite ne-cementite, enamandla amakhulu, ubulukhuni obumaphakathi kanye nepulasitiki ethile. usimende ungasatshalaliswa ngendlela eyimbudumbudu ku-matrix ye-ferrite. Lolu hlobo lwesakhiwo lubizwa nge-spherical pearlite, futhi ukusebenza kwalo okuphelele kungcono.
5. Ledeburite
I-Leutenite iyingxube yemishini ye-austenite ne-cementite, ngokuvamile evezwa njenge-Ld.Isilinganiso sokuqukethwe kwekhabhoni ye-Leutenite sasingu-4.3%.Uma ipholile ibe ngu-727℃, i-austenite ku-leustenite izoguqulelwa ku-pearlite.Ngakho ngaphansi kuka-727℃, i-leutenite iqukethe i-pearlite kanye ne-cementite, ebizwa ngokuthi i-leutenite ekushiseni okuphansi, okuchazwa ngu-Ld '.The I-microstructure ye-Leutenite isekelwe ku-cementite, ngakho izakhiwo zayo zemishini ziqinile futhi ziqinile.
