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: | This article examines the influence of metal powder particle size distribution (PSD) on the quality of parts produced by selective laser melting (SLM). Recent studies demonstrate that optimal powder fractions (typically 15-45 μm) significantly affect part density, surface roughness, and mechanical properties. Both international and Russian research confirms that fine particles (<20 μm) improve resolution but increase agglomeration risks, while coarse particles (>50 μm) may cause incomplete melting. The work highlights the advantages of bimodal PSD for packing density and analyzes challenges with fine powder applications. Current trends focus on developing standardized characterization methods and predictive models for powder behavior in SLM. The article synthesizes key findings from leading international journals and Russian academic sources, providing practical recommendations for powder selection in industrial SLM applications. |
