An analytical description of the interrelation of depletion, segregation and decomposition of a binary alloy in a nanosystem is presented. Size-induced shift of the decomposition cupola appears to be a sum of two terms. The first (related to depletion caused by new phase formation) is inversely proportional to the size R to the power of 3=4. The second (related to segregation at external surface) represents the traditional 1/R dependence. Size-induced ‘splitting’ of the decomposition cupola is also predicted and analytically described.
