Abstract
The criterion of formation of a modulated structure by means of the spinodal mechanism in a spatial distribution of interacting vacancies (as strong concentrators of mechanical stresses) in metals as a target after irradiation is analyzed. For the irradiated body-centered cubic vanadium and tungsten, temperature dependences of the spatial periods of such a structure of the substitutional-vacancies’ subsystem are predicted taking into account the total mixing energies consisting of the energies of the (electro)chemical and strain-induced interactions between vacancies, which are cohesive by the nature in short distances and elastic by character at long distances, respectively.
期刊介绍：
Guided by an international editorial board, Low Temperature Physics (LTP) communicates the results of important experimental and theoretical studies conducted at low temperatures. LTP offers key work in such areas as superconductivity, magnetism, lattice dynamics, quantum liquids and crystals, cryocrystals, low-dimensional and disordered systems, electronic properties of normal metals and alloys, and critical phenomena. The journal publishes original articles on new experimental and theoretical results as well as review articles, brief communications, memoirs, and biographies.
Low Temperature Physics, a translation of the copyrighted Journal FIZIKA NIZKIKH TEMPERATUR, is a monthly journal containing English reports of current research in the field of the low temperature physics. The translation began with the 1975 issues. One volume is published annually beginning with the January issues.
