Ferrite ndi carbon solid solution mu α-Fe, nthawi zambiri amaimiridwa ndi chizindikiro "F."Muchitsulo chosapanga dzimbiri, "ferrite" amatanthauza njira ya carbon solid mu α-Fe, yomwe imakhala ndi mpweya wochepa kwambiri.Imatha kungosungunula pafupifupi 0.0008% kaboni pa kutentha kwa chipinda ndipo imakhala ndi kusungunuka kwa mpweya kwa 0.02% pa 727 ° C.Ferrite amakhala ndi thupi lokhala ndi ma cubic lattice ndipo nthawi zambiri amaimiridwa ndi chizindikiro "F.
Chifukwa chokhala ndi mpweya wochepa, ferrite imasonyeza zinthu zofanana ndi chitsulo choyera, kuphatikizapo ductility ndi kulimba, ndi elongation (δ) pafupifupi 45% mpaka 50%.Ili ndi mphamvu zochepa komanso kuuma, ndi mphamvu yolimba (σb) pafupifupi 250 MPa ndi Brinell hardness (HBS) pafupifupi 80.
Chitsulo chosapanga dzimbiri cha Ferritic, munkhani ya chitsulo chosapanga dzimbiri mumayendedwe ake, makamaka chimakhala ndi ferritic microstructure.Zomwe zili mu chromium zimachokera ku 11% mpaka 30%, ndipo zimakhala ndi thupi lomwe lili ndi thupi la cubic crystal.Chitsulo chachitsulo chosapanga dzimbiri sichigwirizana ndi chitsulo chosapanga dzimbiri cha ferritic kapena ayi.Chitsulo chosapanga dzimbiri cha Ferritic chimadalira kokha ngati, muutumiki wake, chimakhala makamaka ndi ferritic microstructure, yomwe ndi maginito.
Austenite ndi carbon solid solution mu γ-Fe, nthawi zambiri amaimiridwa ndi chizindikiro "A."Imasunga nthiti ya cubic crystal yapakati pa nkhope ya γ-Fe.Ili ndi mpweya wambiri wosungunuka, womwe umasungunuka pafupifupi 0.77% carbon pa 727 ° C ndi mpaka 2.11% carbon pa 1148 ° C.Austenite ndi microstructure yomwe imatha kukhazikika pa kutentha kwapamwamba kuposa 727 ° C.Austenite ndi ductile ndipo ndi microstructure yofunikira pamagiredi ambiri achitsulo ikagwira ntchito yotentha pakutentha kokwera.Austenite si maginito.
