Hi Antonio
I have tried the position of C atom, and i have supposed that could be in
8a,whic is an intersticial position, as Frank says, but you have to
specify the site occupation, which is related to carbon content.
Best wishes.

BTW, it shouldn't need a sophisticated Rietveld refinement to distinguish
between the relative quantities of simple FCC and BCC compounds - some
peaks may overlap almost completely, but others not at all.

Frank is quite correct here. Austenite is gamma-iron, which you can find
immediately with Google or Wikipedia:

Dear Antonio,
as far as I know, austenite is just a solid solution
of a few mole-% of carbon in gamma-iron.
Thus, you essentially need the structure of gamma-Fe,
which is very simple, as it is an fcc metal
(space group Fm-3m, a = 3.6468 A, just one
Fe atom located on 0,0,0).
