... on austenite, which will transform very slowly. Thus when martensite is formed as a result of carbon in austenite in the new form of Fe-N, and at an elevated temperature, the resulting structure means that the nitriding is limited to the ferrite region on the iron-carbon diagram. The bcc lattice structure...
