The idea of the project is to scientifically describe and reveal the mechanisms and regularities of the influence of the initial conditions of reinforcement and shear strains on the structure and properties of the aluminum matrix composites (AMC) in order to obtain new and deepen existing knowledge in the field of theory and technology of rolling and casting. The project is aimed at solving the following problems: – recycling of metallurgical waste; – obtaining light, wear-resistant, strong metal blanks for mechanical engineering; – optimal use of the plasticity resource of a composite material with the development of measures to achieve an optimal balance of strength and plasticity.

Obtaining new and deepening existing knowledge in the field of theory and technology of rolling and casting through the scientific description and disclosure of mechanisms and patterns of influence of the initial conditions of reinforcement and shear rolling on the structure and properties of aluminum matrix composites.

2023 Promising weight percentage compositions of AMCs with scientific justification will be selected and pilot batches of cast and plastically deformed AMC will be obtained. The choice of promising weight percentage compositions of AMC will be carried out with a scientific assessment and analysis of the influence of selected reinforcing materials on the structure and properties of final AMC by means of primary information processing methods and a factorial experiment. The conditions and technological modes of reinforcement, casting and plastic deformation will be established for the preparation and conduct of a laboratory experiment to obtain cast and plastically deformed AMC. 1 (one) article or review will be published in a peer-reviewed foreign or domestic publication recommended by the CQАSHE, and a summary of the project implementation will be provided to the Customer. 2024 The physical-mechanical and tribological properties of cast and plastically deformed AMC will be investigated with scientific analysis and interpretation of the data obtained. Data will be obtained on the physical-mechanical and tribological properties of cast and plastically deformed AMC. Scientific analysis and interpretation of the obtained data on the physical-mechanical and tribological properties of cast and plastically deformed AMC will be carried out. 1 (one) article will be published in a peer-reviewed scientific publication in the scientific direction of the project, indexed in the Science Citation Index Expanded and included in the 1 (first), 2 (second) and (or) 3 (third) quartile by the impact factor in the Web database of Science and (or) having a CiteScore percentile in the Scopus database of at least 50 (fifty), and the Customer will be provided with a summary of the project implementation. 2025 The structures of the phase of cast and plastically deformed AMC will be investigated with scientific analysis and interpretation of the data obtained. Data will be obtained on the structure and phases of cast and plastically deformed AMC. Scientific analysis and interpretation of the obtained data on the structure and phases of cast and plastically deformed AMC will be carried out, and recommendations will be developed for optimizing the composition through a factorial experiment (final). 2 (two) articles will be published in peer-reviewed scientific publications in the scientific direction of the project, indexed in the Science Citation Index Expanded and included in the 1 (first), 2 (second) and (or) 3 (third) quartile by the impact factor in the Web database of Science and (or) having a CiteScore percentile in the Scopus database of at least 50 (fifty), and the final report on the project will be submitted to the Customer.

The most optimal ranges of variation of AMC compositions providing increased strength and plastic properties have been identified. Analysis of experimental data showed that when 200 g of TIB 2 and 170 g of SiO2 are added to 1000 g of alloy, the maximum value of the ultimate strength of AMC (σb = 500÷510 MPa) is ensured. A drawing has been developed and cone-shaped rolls with a convex working surface have been manufactured for slotting the obtained AMCs in order to impart additional enhanced mechanical properties and distribute them evenly over the entire volume of the workpiece.
