Below 912 °C (1,674 °F), iron has a body-centered cubic (bcc) crystal structure and is known as α-iron or ferrite. It is thermodynamically stable and a fairly soft metal. α-Fe can be subjected to pressures up to ca. 15 GPa before transforming into a high-pressure form termed ε-Fe discussed below. Magnetically, α-iron is paramagnetic at high temperatures. However, below its Curie … WebThe largest interstitial sphere that would just fit has a radius of 0.52(10)-8 cm. therefore, austenite will have a greater solubility for carbon than ferrite.

Ferrites are usually non-conductive ferrimagnetic ceramic compounds derived from iron oxides such as hematite (Fe2O3) or magnetite (Fe3O4) as well as oxides of other metals. Ferrites are, like most other ceramics, hard and brittle. Web10 jan. 2016 · However silicon and other alloying elements can considerably change the maximum solubility of carbon in austenite. Therefore, in exceptional cases, alloyed cast iron with less than 2 % C can solidify with a eutectic structure and therefore still belong to the family of ‘cast irons’. WebFerrite (α): Iron in a BCC structure. Maximum solubility of carbon in ferrite is low (0.02%C). Austenite: Iron with a FCC structure. Due to FCC structure, more carbon atoms can be accommodated. Maximum solubility of carbon in austenite is 2.11%. Cementite (or iron carbide): This forms when solubility of carbon in solid iron is exceeded. Fe friends of the earth limited
