Abstract
Dendritic liquation of admixtures of metal is heterogeneity of composition in the axes of dendrite and interdendritic area. Two tendencies of liquation of elements are found in the alloys of iron: in environments-him for all elements a liquation diminishes at the increase of concentration of addition; for a from-efficient element a liquation is increased with the concentration of element. The new order of location of elements is specified among superficial activity of metals in liquid iron. This order can be used for the choice of elements for the desorption of harmful admixtures from the surface of solidifi able crystals of metal.
Keywords
