Abstract
This paper presents limit values of equilibrium distribution coefficients of admixtures in basic metals and the periodical correlation dependences of the distribution coefficients. For high melting-point metals activation neutron analysis, X-ray topography and SSMS were applied to establish effective distribution coefficients of selected admixtures in metals as well as the structural perfection of single crystals.
