description: The given work is devoted to the construction of a model that makes it possible to determine the size of the precipitates of the Î³' - phase forming in a permeated solid solution during direct laser deposition, depending on the processing modes. This research set the following goals: 1. Solution of the problem of propagation of thermal fields from a distributed laser source. In this case, the problem of heating the particles of the filler powder and the problem of heating the surface of a semi-infinite body with a laser source are solved separately. 2. Solving the problem of growth of the intermetallic phase of Ni3Al, jointly solving the problem of changing the concentration of Al on the surface of the growing precipitate. 3. Perform verification of the constructed model based on the research data. The analysis of the results showed that the constructed model gives satisfactory results. However, large deviations from the experimental values are observed in the modes characterized by high power of the laser source. These deviations correlate with the amount of carbides that fall out, which in turn is associated with high processing temperatures in these modes. To refine this model, it is necessary to include in the model description the formation of different phases with their mutual influence through the concentration of impurities in a solid solution, as well as the complex doped state of the Î³'-phase.
