MOSSBAUER STUDIES OF 12Cr18Ni10Ti STEEL SAMPLES EXPOSED TO RADIATION WITH 57Fe IONS

Abstract

The phase-structural transformations were studied by the X-ray diffraction analysis, scanning electron microscopy and Mössbauer spectroscopy in transmission geometry and in the backscattering mode in the electronic channel in austenitic stainless steel 12Cr18Ni10Ti irradiated with 57Fe ions in the heavy ions accelerator. The X-ray diffraction method and Mössbauer spectroscopy showed the austenitic mono-phase in the original steels. The austenite remains the dominant phase in the irradiated samples, and the radiation initiated martensitic phase is available in small amounts.
