1. Ferrite
Ferrite shine ingantaccen bayani mai tsaka-tsaki wanda aka kafa ta carbon wanda aka narkar da shi a cikin -Fe. Ana bayyana shi sau da yawa kamar ko F. Yana kula da tsarin alpha -Fe.Ferrite yana da ƙananan ƙwayar carbon, kuma kayan aikin injiniya yana kusa da waɗanda ke da ƙarfe mai tsabta, babban filastik da taurin, da ƙananan ƙarfi da taurin.
2. Austenite
Austenite ne A interstitial m bayani na carbon narkar da a -Fe, yawanci bayyana a matsayin ko A. Yana kula da fuska-tsakiyar cubic lattice tsarin gamma-Fe.Austenite yana da mafi girma carbon solubility fiye da ferrite, da inji Properties suna halin da kyau plasticity. , Ƙarfin ƙarfi, ƙarancin ƙarfi da sauƙi na lalata filastik.

3. Siminti
Cementite wani fili ne da aka samar da ƙarfe da carbon, wanda tsarin sinadarai shine Fe3C.Ya ƙunshi 6.69% carbon kuma yana da tsarin tsari mai mahimmanci. Siminti yana da tsayin daka sosai, ƙarancin filastik, kusan sifili, kuma lokaci ne mai wuya kuma mai gatsewa. Cementite yana taka rawar ƙarfafawa a cikin ƙarfe na carbon. A cikin ƙarfe-carbon gami, mafi girman abun ciki na carbon, mafi yawan siminti, mafi girma da taurin da ƙananan filastik na gami.
4. Pearlite
Pearlite shine cakuda inji na ferrite da siminti, yawanci P.Matsakaicin abun ciki na carbon na pearlite shine 0.77%, kuma kayan aikin injinsa yana tsakanin ferrite da cementite, tare da babban ƙarfi, matsakaicin tauri da wasu filastik.Ta hanyar maganin zafi, za a iya rarraba cementite a cikin nau'i na granular akan matrix ferrite. Irin wannan tsarin ana kiransa pearlite mai siffar zobe, kuma cikakkiyar aikinsa ya fi kyau.
5. Ledeburite
Leutenite shine cakuda inji na austenite da siminti, yawanci ana bayyana shi azaman Ld.Matsakaicin abun ciki na carbon Leutenite shine 4.3% lokacin da aka sanyaya zuwa 727 ℃, austenite a cikin leustenite za a canza shi zuwa pearlite.Don haka a ƙasa 727 ℃, leutenite ya ƙunshi pearlite. da siminti, wanda ake kira leutenite a ƙananan zafin jiki, wanda Ld ya nuna. The microstructure na Leutenite yana dogara ne akan siminti, don haka kayan aikin injiniya suna da wuya kuma suna gatsewa.
