The influence of hydrogen and helium impurities on physical and mechanical properties of EP-450 ferrite steel has been studied. The techniques of elastic recoil detection analysis, Rutherford backscattering, acoustic emission, acoustic energy dissipation rate measurements, magnetic and eddy-current methods were used. Microhardness of steel samples containing hydrogen and helium has been studied by nanoindentation. Microscopic investigation of the steel surface after hydrogenation and after exposing to monoenergetic 40-keV helium ions has been performed.
