Austenite and ferrite Austenite was originally used to describe an iron carbon alloy in which the iron was in the face centred cubic gamma iron form It is now a term used for all iron alloys with a basis of gamma iron Austenite in iron carbon alloys is generally only evident above 723°C and below 1500°C depending on carbon content
1 Ferrite Iron which contains little or no carbon is called ferrite It is very soft and ductile and is known as alpha iron by the metallurgists Ferrite is present to some extent in a great range of steels particularly those low in carbon content and it is also present in soft cast iron Ferrite does not harden when cooled rapidly
