摘要：
Austenitic high nitrogen Fe-19Cr-19Mn-0.9N steel was studied by means of Mossbauer analysis and neutron diffraction and small-angle neutron scattering (SANS) after solution treatment at 1125 degrees C and ageing at 250-350 degrees C. The redistribution of nitrogen atoms in austenite after ageing was detected in Mossbauer measurements. SANS was observed in annealed and egeined samples characterizing an existence of the inhomogeneities in steel of atomic and magnetic nature. The linear size and shape of inhomogeneities is estimated on the basis of analysis of the integral parameters of scattering curves.
