Modification of single crystal stainless steel structure (Fe-Cr-Ni-Mn) by high-power ion beam

Samples of Fe-56-Cr-18-Ni-16-Mn-10 single crystals of (111) and (100) cryst allographic planes and 12 x 12 x 2 mm(3) dimensions have been treated by a proton beam of I MeV energy. Analysis of their structure and the element co mposition has been performed using the methods of transmission electron mic roscopy, scanning electron microscopy, atomic-force microscopy, Rutherford back scattering of ions. Also we applied micro-hardness tests, those of wea r resistance, and corrosion resistance. Numerically we solved the problem o f determining the amount of evaporated material.
