Abstract

In the present research, the evolution of fractal aggregates in systems with conserved order parameter is studied. The aggregates are generated by diffusion limited aggregation (DLA). This model describes such important processes as annealing of dendrite inclusions in solids, healing of cracks in ceramics, temperature-induced transformations in composites, relaxation of rough surfaces, aging of colloid particles, etc. It is shown that the evolution in fractal media differs significantly from the evolution from the initially homogeneous state and leads to the different values of the scaling exponent.
