Abstract
Impurities are known to play an important role in hardening processes and are widely used in metallurgy for improving the quality of castings. However, the nature and mechanism of their effect have been insufficiently studied. This impedes development of a theory of modification. Therefore, the choice of modifying additives is made empirically in the majority of cases. Elucidation of the effect of soluble and insoluble additives on the kinetics of formation and growth of crystals and on their morphology is crucial from the viewpoint of primary structure modification since formation of a casting is determined namely by these factors. Investigation of these questions has a rather lengthy history. A definite contribution to progress on this problem has been made by the studies carried out at the Metal Physics Institute of the Academy of Sciences of the Ukrainian SSR. Fundamental concepts about the role and mechanism of the effect of impurities on crystallization processes and formation of cast structures have been based on these studies. The present work is also concerned with these.
