Аннотация: The purpose of the research is to study the mechanisms of structural and phase transformations in superficial layers of transitive metals at ion implantation and further heat treatment. As base methods of the structure research of irradiated and non-irradiated materials have been used the approved methods of X-ray-structure analysiПоказать полностьюs with the use of narrow sliding monochromatic CuK-radiation and Rutherford backscattering. The experimental results allow to make the following conclusions: the basic laws of structural and phase transformations in the transitive metals (tungsten and tantalum) are established at their implantation by the ions of the elements which form introduction phases (nitrogen, oxygen and phosphorus); it is revealed that the mechanism of structural and phase transformations is determined, generally by the dimensional factor and slightly depends on physical and chemical properties and kinetic parameters of bombarding elements; it is revealed that the implantation of tungsten and tantalum by oxygen ions results in formation of highly packed structures which have been identified in the work as W2O and TaO oxides.
