Iron-Steel Diagram : Comprehension
(OP)
According to the Iron-Steel Diagram, over a certain temperature, the initial Iron/Steel structure is complete transformed in Austenite.
My question is :
For the Steel with very low carbon content (for example for pure ferrite steel), where does the carbon come from to complete the transformation of each austenite structure ?
By definition, ferrite structure only possess a body-centered cubic structure with only 1 carbon element, as the autenite structure (face-centered cubic) possess 6 carbon elements....
Thanks in advance !

Iron does not require the presence of Carbon to transform into austenite (FCC structure). Pure iron will transform from ferrite (alpha, BCC) into austenite (gamma, FCC) above ~ 930 C. Here is a link with some additional information:
