Samara University Repository
Welcome to the Samara University repository!
This is an open electronic archive created to preserve and disseminate the scientific results of our university. The works of researchers, faculty members, and students are available to everyone for academic and research purposes.
The repository contains dissertations, research articles, educational and methodological materials, monographs, and regulatory documents. The collections cover a wide range of fields: from aerospace technologies, engine engineering, and computer science to history, linguistics, mathematics, and ecology. The archive brings together the scientific heritage of the university, including materials prepared during the period of Samara State Aerospace University and Samara State University.
Looking for publications by author, title, date, or subject? Full-text search will provide relevant results. Want to explore the academic life more closely? Browse materials by the universityâs organizational units.
Descriptions of all publications and articles available in the repository can be found in the libraryâs electronic catalog. Staff and students can log in via the menu "Login -> My Resource Archive" using their personal account credentials (SSAU_id).
Use the archive for study, research, and professional development!

| Abstract: | The paper presents the results of experimental studies on the effect of laser power and heat treatment on the microstructure and mechanical properties of heat-resistant alloy EP648 samples obtained by direct laser deposition. It is shown that increasing the laser power from 1200 to 2000 W improves the melting degree of powder particles and enhances the mechanical characteristics. The optimal parameters for achieving high-quality parts are determined: laser power of 1800–2000 W and heat treatment regime including quenching at 1180±10°C followed by aging at 900±10°C. These findings can be applied in additive manufacturing of gas turbine engine components requiring high strength and thermal resistance. |
