Abstract
Macro- and micro-inhomogeneity of composition of hard magnetic YuNDKT5 AA alloy single crystal ingots grown at rates 1-10 mm/min has been stu died by chemical and X-ray electron probe analyses. Dendritic segregat ion of the alloy constituents vs growth rate dependency was found to b e not monotonous. At the same time the average chemical composition al ong the vertical extent of the ingot in all cases remains virtually co nstant.
