The kinetic process to reach the equilibrium state of lattice defects is characterized by an aggregation of these defects. The formation of the precursors of the aggregates, the so called critical nuclei, can be investigated by Monte Carlo simulation. But in many cases the exact interaction potential between the movable defects in the lattice and the nucleus is unknown. Therefore such simulations were carried out for different typical interaction parameters. Conclusions concerning the general behaviour were derived. The calculations allow especially an estimation of the influence of strength of the potential and temperature on the number of defects forming a critical nucleus.
