As determined, with the help of a constant magnetic field it is possible to control the size of the grains of the cast alloy, to enhance the efficiency of the modifying elements, and to affect the quantity of alloying and impurity components contained in the grains of the alloy matrix. Specific features of the distribution of Cu in grains of Al $\alpha$-solid solution, treated with a constant magnetic field, which determine their micro-hardness, are established. As found, the constant magnetic field reduces a dendritic liquation of copper.

Key words: Al–Cu alloy, components’ concentration in grains, micro-hardness, constant magnetic field.
