Ferrite bụ ihe ngwọta siri ike carbon na α-Fe, nke akara "F" na-anọchi anya ya.N'imeigwe anaghị agba nchara, "ferrite" na-ezo aka na carbon siri ike ngwọta na α-Fe, nke nwere obere carbon solubility.Ọ nwere ike ịgbari ihe dịka 0.0008% carbon na okpomọkụ ụlọ ma nwee oke carbon solubility nke 0.02% na 727°C.Ferrite na-edobe ihe owuwu cubic lattice nke gbadoro ụkwụ na ya ma akara “F.
N'ihi ọdịnaya carbon ya dị ala, ferrite na-egosipụta ihe ndị yiri ígwè dị ọcha, gụnyere ezigbo ductility na siri ike, yana elongation (δ) nke ihe dịka 45% ruo 50%.Ọ nwere ike dị ala na ike siri ike, yana ike tensile (σb) nke ihe dịka 250 MPa yana ike ike Brinell (HBS) nke ihe dịka 80.
Ferritic igwe anaghị agba nchara, n'ọnọdụ nke igwe anaghị agba nchara na ya ọrụ steeti, bụ isi mejupụtara a ferritic microstructure.Ọdịnaya chromium ya sitere na 11% ruo 30%, yana o nwekwara nhazi cubic crystal nke gbadoro ụkwụ na ya.Ọdịnaya igwe anaghị agba nchara anaghị emetụta ma ọ bụ igwe anaghị agba nchara ferritic ma ọ bụ na ọ bụghị.Igwe anaghị agba nchara Ferritic na-adabere naanị na ma, na steeti ọrụ ya, ọ nwere nke kachasị nke microstructure ferritic, nke bụ magnetik.
Austenite bụ ihe ngwọta siri ike carbon na γ-Fe, nke akara "A" na-anọchi anya ya.Ọ na-edobe lattice cubic crystal nke γ-Fe dabere na ihu.Ọ nwere oke carbon solubility dị elu, na-agbaze ihe dịka 0.77% carbon na 727°C yana ruo 2.11% carbon na 1148°C.Austenite bụ microstructure nke nwere ike kwụsie ike naanị na okpomọkụ dị elu karịa 727°C.Austenite bụ ductile na ọ bụ microstructure achọrọ maka ọtụtụ akara nchara mgbe ejiri ọkụ na-arụ ọrụ na okpomọkụ dị elu.Austenite abụghị magnetik.
