Using a residence-time Monte Carlo algorithm, we have simulated microstructural evolution in two-dimensional, ternary (ABC) alloys in which a B-rich (P) and a C-rich (γ) phase precipitates out simultaneously from a supersaturated A-rich (α) parent phase. We present our results for an alloy containing 5% B and 5% C. While the microstructure during early stages contains both isolated particles (of β and γ) and composite particles (i.e., β and γ particles which are in contact with each other), it contains mostly composite particles during late stages. This result indicates that the presence of composite particles in a microstructure is mainly due to their enhanced stability with respect to isolated particles during coarsening. The coarsening kinetics obeys the classical $R^3\propto$t temporal power law, indicating that this law is valid even when the particles are in a composite form
