The kinetic theory of diffusion phase transformations is used to calculate the time it takes for the ε phase to form in Fe-Cu alloys at various temperatures. The fine structure and hardness of alloys containing from 0.6 to 5.5 at % Cu and aged in the martensite state are studied. The calculated and experimental data are in good agreement. The cooling rate of copper-bearing alloys that provides the maximum hardness upon the precipitation of ε-phase particles of a given size is estimated. © 2010 Pleiades Publishing, Ltd.
