description: This thesis is dedicated to the study of the macrostructures of gas turbine blades, the investigation of the manufacturing process using investment casting, and the development of a highspeed directional solidification technology to achieve either a single-crystal or directional columnar structure. During the research, the advantages of such blades over those with equiaxed polycrystalline structures were examined. The work was conducted at the enterprise Â«Melting PointÂ» LLC, which has the appropriate equipment to perform operations for each stage of the technological cycle of gas turbine blade production. The conditions and modes of each operation were developed, and a comparative analysis was made between the actual production processes and those theoretically described in literature sources. As a result, blades with single-crystal and directional columnar structures were obtained through the developed technological process. During the development of these macrostructures, conditions differing from those described in theoretical sources were identified and incorporated into the process.
