WebFerrite or α-ferrite is a body-centered cubic structure phase of iron which exists below temperatures of 912°C for low concentrations of carbon in iron. α-ferrite can only dissolve up to 0.02 percent of carbon at 727°C. This is because of the configuration of the iron lattice which forms a BCC crystal structure. WebThe solubility limity of carbon in austenite (FCC Fe crystal) is 2.14% at eutectic temperature... It means that the solubility limit of carbon in austenite (FCC) is more than …
WebJul 4, 2016 · Martensitic transformation paths. During the martensitic transformation, the coordinated movement of atoms leads to a specific OR between the parent austenite (γ) and newly formed ferrite (α) lattices, in which a pair of close-packed planes in the α and γ phases are parallel or nearly parallel.In 1924, Bain proposed the fcc to bcc crystal structure … Web(a) FCC is a more close packed structure yet solubility of carbon in austenite, which is FCC is, higher than that in ferrite, which is BCC. Why is it so? (2 marks) (b) Consider 10 kg of austenite containing 0.65 wt % C cooled slowly.
