Question

Carbon solubility on gamma iron is more then alpha iron

Answer 1

Austenite (γ): Austenite is a face centred cubic structure (fcc). It is stable at temperatures above 723oC depending upon carbon content. ... The maximum solubility of carbon in the form of Fe3C in iron is 6.67%. Addition of carbon to iron beyond this percentage would result in formation of free carbon or graphite in iron.
