Process of the relaxation of a cluster with an intrinsic pore was investigated for different phases of a cluster. Main parameters, determining pore dissolving time were found. In particular, it was shown that there exists critical temperature Tc, that depends on pore and cluster sizes. Below Tc nonequilibrium process does not destroy solid state of the cluster and pore life time increases sharply. Process of pore relaxation in this case is characterized by a free energy barrier.
