Abstract
Structure formation processes were considered during polymorphic transformations in metals. A model of polymorphic transitions in metals with face-centered cubic (fcc), hexagonal closed-packed (hcp), and body-centered cubic (bcc) lattices was proposed from the standpoint of the cluster approach. The model is based on the idea of preserving the volume of octahedral cluster elements of the corresponding lattices. It was found that calculation data were in good agreement with the model representations proposed in the paper.
