Developing the Isotopic Technique of Studying Diffusion in Metals
The authors study the experimental conditions for determining the diffusion mobility of impurities in solid bodies. Considering these conditions shows the need to continue developing the familiar Gruzin technique. In studying a large group of elements in metallic beryllium, Gladkov’s research group analyzed the effects of refining, which includes the absorption of radiation of an isotope by a sample and the dynamics of changes in the source in the process of diffusion annealing. Mathematical tools for considering these effects are developed. It is concluded that the new ways of processing the experimental results can be used in studying the diffusion characteristics of a wide range of contaminants in solid matrices.
