description: This work is devoted to the study of metallurgical and thermal deformation processes occurring during direct laser deposition (DLD) of products from metallic powder material 09CrH2MoCu, designed for operation at low temperatures. Based on these findings, a technology was developed for manufacturing the product using the DLD method. The purpose of this work is to manufacture the Hemisphere detail by direct laser deposition. To achieve this goal, technological parameters were determined for defect-free sample deposition, tests were carried out to determine the mechanical properties of laboratory samples, and a recommendation was given for subsequent heat treatment. The deformations that can occur during the DLD-process are calculated. Based on the calculations, the geometry of the part has been adjusted to ensure the necessary size of the future product. The Hemisphere was made by direct laser deposition.
