Изменение механических свойств мартенситно-стареющих сталей при ионно-пучковом наноструктурировании поверхностного слоя

The change of strength and plastic properties of maraging steel EI122 at surface layer nanostructuring by ion beams (Al+B) has been studied. The effect of plasticity and strength simultaneous increase was ascertained. Its size depends on original and post-implantation sample thermal treatment and radiation level. Structural-phase state of surface layer of original steels and those nanostructured by ion beam was studied by the methods of transmission electron microscopy and X-ray-structural analysis. Mechanisms of the observed effect were discussed on the basis of the obtained results.
