Thermodynamic regularities of the transformation of a lamellar shape into a spherical one is analyzed on the basis of the comparison of interface energies of spheres and disks. It is revealed that the motive force of spheroidization in two‐phase systems with a high level of anisotropy occurs during high‐temperature deformation due to developing recrystallization processes. In systems with a low level of interface energy anisotropy the motive force considerably increases due to recrystallization. The causes of a specific behaviour of systems consisting of phases with different types of interatomic bonds are noted.
