Annotation The paper shows that the ion bombardment (IB) by low-energy ions essentially influences the behavior of a specimen under tension testing changing strength and ductility of the item as a whole though the same properties of metal remain in its core. IB also increases fatigue strength and can be used for improving the ductility of sheet steels. This treatment is especially effective for items with technological stress concentrators and is recommended as a very effective and simple method of improving their structural strength. The phenomenon is explained by surface nanostructuring during ion bombardment.
