description: This work is devoted to the study of aluminum-matrix composite alloys with combined radiation-protective properties (neutron-absorbing and gammascattering). Tasks that were solved during the research: 1. Search for patents and scientific literature in the field of research and development of aluminum-matrix composites with neutron-absorbing and gammascattering properties; 2. Obtaining the matrix alloy ÐÐ7Ð¿Ñ, doped with gadolinium; 3. Identification of gamma-scattering elements and compounds, preliminary composition of the experiment plan; 4. Development of a method for obtaining and introducing dispersed particles with Î³-scattering properties using powder metallurgy methods; 5. Development of technology for producing cast billets from composites that contain "heavy" dispersed PbWO4 particles and B4C nanoparticles; 6. obtaining premixes (dry mixtures) of base alloy chips and dispersed and nanoparticles, their further briquetting; 7. Getting the cast blanks for the manufacture of test specimens. The work was carried out on the basis of the Kurchatov Institute - Prometheus research center, where the radiation-protective and gamma-scattering properties of the obtained composites were evaluated. The aluminum matrix composite being developed should serve as a protective shield against ionizing radiation from nuclear reactions. The material absorbs a wide energy spectrum of radiation due to the content of B and Gd and is suitable for protection against mixed radiation sources. In the process of neutron absorption, the excess energy is emitted as a gamma quantum, so additives were used in the form of dispersed fillers of lead tungstate.
