I am looking for cif files for austenite and I
didnt find it in WEB free database or in ICSD database.
Frank is quite correct here. Austenite is gamma-iron, which you can find
immediately with Google or Wikipedia:
Small amounts of carbon or hydrogen dissolved in gamma-iron, as reported
in ICSD, is not going to change the X-ray pattern, since Fe-scattering
will dominate. ICSD only reports what people publish. I believe the 1970
X-ray paper on austenite listed in ICSD only reports the lattice
constants, and doesn't actually claim to locate the carbon.
