Abstract: In this paper experiments on crystallization from melts and results of analysis of the morphology of formed crystal structures are discussed. Some examples of forming complex dendritic formations are shown. Different types of the crystal morphology arise in dependence on the duration of heating and the energy of the acting radiation. Models of the distribution of crystallization centers and the growth of an individual cluster under the diffusion process were modelled by the methods of cellular automata. The relationship between the morphology and the model parameters is analyzed.
Keywords: laser heating, metal surface modification, crystallization, fractal, dendritic crystals, diffusion-limited aggregation, cellular automata.
