1. I-ferrite
I-Ferrite sisisombululo esiqinileyo se-interstitial esenziwe yikhabhoni enyibilike kwi -Fe.Ihlala ichazwa njenge-F.It igcina i-bulk centered cubic lattice structure ye-alpha -Fe.Ferrite inomxholo ophantsi wekhabhoni, kunye neempawu zayo zomatshini zisondele kwintsimbi ecocekileyo, iplastiki ephezulu kunye nokuqina, kunye namandla aphantsi kunye nobunzima.
2. I-austenite
I-Austenite sisicombululo esiqinileyo se-interstitial sekhabhoni enyityilisiweyo kwi-Fe, ngokuqhelekileyo ibonakaliswe njenge-A.Igcina i-cubic lattice ejongene nobuso obuphakathi kwe-gamma-Fe. , amandla aphantsi, ubunzima obuphantsi kunye ne-deformation yeplastiki elula.

3. Isamente
I-Cementite i-compound eyenziwe yintsimbi kunye nekhabhoni, i-formula yayo yeekhemikhali yi-Fe3C.Iqulethe i-6.69% yekhabhoni kwaye ine-crystal structure eyinkimbinkimbi.I-cementite inobunzima obuphezulu kakhulu, i-plasticity embi, phantse i-zero, kwaye iyinqanaba elinzima kunye ne-brittle. I-Cementite idlala indima yokomeleza kwi-carbon steel.Kwi-iron-carbon alloys, i-carbon content, i-cementite eninzi, iphakamileyo yobunzima kunye ne-plasticity ye-alloys.
4. IPearlite
I-Pearlite ngumxube womatshini we-ferrite kunye ne-cementite, ngokuqhelekileyo ichazwa ngu-P.I-carbon content ye-pearlite yi-0.77%, kunye neempawu zayo zomatshini ziphakathi kwe-ferrite kunye ne-cementite, ngamandla amakhulu, ubunzima obuphakathi kunye neplastiki ethile. i-cementite inokuhanjiswa kwifom yegranular kwi-matrix ye-ferrite.Olu hlobo lolwakhiwo lubizwa ngokuba yi-spherical pearlite, kwaye ukusebenza kwayo okubanzi kungcono.
5. Ledeburite
I-Leutenite ngumxube womatshini we-austenite kunye ne-cementite, ngokuqhelekileyo ibonakaliswe njenge-Ld.I-carbon content ye-Leutenite yayingu-4.3%.Xa ipholile kwi-727℃, i-austenite kwi-leustenite iya kuguqulwa ibe yi-pearlite.Ngoko ngaphantsi kwe-727℃, i-leutenite iqukethe i-pearlite kunye ne-cementite, ebizwa ngokuba yi-leutenite kwiqondo lokushisa eliphantsi, elichazwe nguLd '.I-microstructure ye-Leutenite isekelwe kwi-cementite, ngoko ke iipropati zayo zomatshini zinzima kwaye zibuhlungu.
