The results of the study of qualification of the crystal form of metallic fabrics after exhaustive external influences on the nuclear-spatial level are bestowed. The aim of the work is to explain the effectiveness of the use of field issuance and atomic probe procedures for the study of nanomaterials and nano-structural states emergent in volumes of metals and alloys subsequently powerful outside influences, including dissemination exposure. Atom Probe Tomography (APT or 3D Atom Probe) is the only matters analysis system that offers extensive potential for both three-dimensional image and atomic-level synthetic composition calculations (resolution of about 0.1–0.3 nm exhaustive and 0. 3–0.5 nm horizontally). The original results show the chance of three-dimensional rebuilding of the elemental arrangement of mechanically combined alloys for the study of modification of the tiny structure. The styles of irradiation for the establishment of amorphous states in the near-surface capacities of platinum have happened determined. It has happened established that the wonder of amorphisation of metals in surface volumes happens up to the sample insight of 12 nm at the increase of fluence to 1018 ion/cm2 and the specified strengthes of irradiation. It has happened determined that the type of the crystalline form of the boundary region of even defects in metal fabrics directly depends on the type of outside influence. The width of the border regions at hardware partition boundaries has existed found to change within limits 0.8 and 1.5 nm depending on the type of passionate external impact at which point they were exposed.
