The formation of carbon clusters in ferrite is investigated by the simulation of random motion of carbon particles in a cubic primitive model lattice at different annealing temperatures. All computer runs are repeated to average the results. An interaction potential is assumed between the particles precipitated in the formed cluster and the particles in the matrix. Additionally a decay of the cluster is allowed. A cluster of critical size is formed if the probability of decay is lower than the precipitation rate. The critical size calculated depends on the annealing temperature as the results show unambigously.
