Qhov sib txawv tseem ceeb ntawm austenite thiab ferrite yog tias austenite muaj lub ntsej muag-centered cubic configuration ntawm gamma hlau whereas lub ferrite muaj lub cev-centered cubic alpha hlau configuration. Ntxiv mus, austenite muaj qhov zoo li hlau thaum ferrite muaj qhov zoo li ceramic.
Austenite thiab ferrite yog allotropes ntawm hlau. Ntxiv mus, cov allotropes muaj nyob rau ntawm qhov sib txawv kub. Cov allotropes ntawm hlau muaj npe txawv li alpha hlau, beta hlau, gamma hlau thiab delta hlau. Cov allotropes no muaj nyob rau ntawm tus qauv siab. Muaj qee qhov allotropes ntawm hlau uas muaj nyob rau ntawm qhov siab siab. Piv txwv li, epsilon hlau (tseem hu ua 'hexaferrum').
Austenite yog dab tsi?
Austenite yog ib qho allotrope ntawm hlau hu ua gamma-phase-hlau. Yog li ntawd, nws yog xim hlau thiab tsis yog hlau nplaum. Qhov no allotrope tshwm sim nyob rau hauv sib txawv hlau alloys ntawm txawv kub. Piv txwv li, nyob rau hauv lub tiaj-carbon steel, qhov no allotrope tshwm sim ntawm 727 ° C thaum nyob rau hauv stainless hlau, nws muaj nyob rau hauv chav tsev kub. Lub cubic qauv ntawm no allotrope yog lub ntsej muag-centered cubic qauv. Thaum peb hloov qhov kub ntawm 912 ° C mus rau 1, 394 ° C, qhov no austenite allotrope tsim los ntawm lwm cov allotrope hu ua ferrite. Peb hu cov txheej txheem no austenitization. Austenite kuj yog mos thiab ductile. Raws li qhov tshwm sim, nws tuaj yeem yaj ntau cov pa roj carbon ntau hauv nws cov tshuaj tov.
Ferrite yog dab tsi?
Ferrite yog ib qho allotrope ntawm hlau hu ua alpha-phase-hlau. Nws muaj qhov zoo li ceramic, thiab nws yog paramagnetic. Nws muaj lub cev-centered cubic qauv. Tsis tas li ntawd, kev sib cais ntawm carbon nyob rau hauv no allotrope yog pluag.

Tsis tas li ntawd, cov khoom no yog cov khoom siv zoo li ceramic. Nws muaj ntau yam kev siv hauv cov khoom siv hluav taws xob. Vim nws yog ib qho nyuaj thiab nkig, peb tuaj yeem pom cov hlau no hauv cov hlau cam thiab steel.
Qhov txawv ntawm Austenite thiab Ferrite yog dab tsi?
Austenite yog ib qho allotrope ntawm hlau hu ua gamma-phase-hlau. Nws muaj lub ntsej muag xim hlau, thiab nws yog qhov muag muag. Ntxiv mus, nws yog ductile thiab non-magnetic. Ferrite yog ib qho allotrope ntawm hlau uas peb hu ua alpha-phase-hlau. Nws muaj lub ntsej muag zoo li ceramic, thiab nws nyuaj. Tsis tas li ntawd, nws yog nkig thiab paramagnetic. Qhov no yog qhov txawv ntawm austenite thiab ferrite.
Summary – Austenite vs Ferrite
Austenite thiab ferrite yog ob lub allotropes ntawm hlau. Qhov txawv ntawm austenite thiab ferrite yog tias austenite muaj lub ntsej muag-centered cubic configuration ntawm gamma hlau whereas lub ferrite muaj lub cev-centered cubic alpha hlau configuration.
