Abstract
An estimate of the vacancy migration energy in alloys is obtained. Since atoms of different substitution elements need different energy to hop to a neighboring vacant site, the vacancy migration energy is usually evaluated using some averaged characteristic. Based on the data of previously conducted dilatometric experiments, the vacancy migration energies of Ni, Fe, and Cr in the ChS68 and EK164 steels are determined and used to calculate the pore growth rate in these steels under neutron irradiation at the beginning of the unsteady swelling stage.
