Abstract: Janus particles are often formed during phase transformations in small volumes. When modeling, as a rule, simple configurations are limited. The mechanical equilibrium arising from the compensation of surface forces is considered. It is shown that the geometric characteristics of Janus particles depend significantly on the volume fraction of coexisting phases. The equilibrium shapes of particles are given for different volume fractions of phases at a constant surface tension of the interphase boundaries. A conclusion is made about the need to take into account changes in geometric parameters when modeling Janus particles with a changing degree of stratification.

Keywords: phase transformations, surface effects, mechanical equilibrium, Janus particles.
