The distribution of heavily post-critical nucleation centers in the nucleation kinetics subject to the macroscopic flow effect has been successfully obtained. Examples of rotary and convective motions during the centrifugal casting are considered. The obtained distribution has been confirmed by an experimental investigation of the composite material AK12 (boron carbide (B4C)) crystallization.
