Decomposition of a homogeneous oversaturated solid solution under periodic changes of temperature (thermal cycling) is investigated by example of nucleation and growth of copper clusters in FeCu$_{1.34\%}$ alloy in the range of 600—800 K. As shown, the different modes of thermal cycling, which are essentially different in the heating and cooling rates, lead to similar results–to acceleration of ageing of nonequilibrium solution in comparison with isothermal annealing at the temperature within the interval at issue.

Key words: iron—copper alloy, thermocycling, nucleation, diffusion decomposition, numerical solution.
