STRUCTURAL IMPERFECTIONS OF METALS DURING RECRYSTALLIZATION,
Abstract
An investigation was made of the heredity of metal structure during recrystallization and grain growth. The investigation method combined autoradiographic and microstructural analyses. The degree of perfection of separate structural zones after recrystallization was determined by their diffusion permeability, as a defective structure has a higher permeability for diffusive atoms. Diffusive saturation of specimens by a radioactive tracer was investigated by means of special donors after recrystallization. The stability or degree of imperfection of the boundaries of initial grains after recrystallization was investigated depending on the degree of purity of the material and recrystallization conditions. 'Sulim' iron, as well as iron with diffused atoms of various elements (such as tin, tungsten) at the boundaries were investigated for saturation of the boundaries of initial grains with impurities.
