Pulsed ion beam induced changes in a submicrocrystalline structure of the near surface layers of austenite steel

The topography and structure of near surface layers of submicrocrystalline austenite steel 12Kh18N10T after pulsed irradiation with C+ and H+ ions were investigated. Ion beam irradiation resulting in modification of the near surface layer and formation of a structure close to an equiaxed ultrafine grain structure with a high fraction of high-angle boundaries were shown.
