The idea of the project lies in the environmentally and cost-effective production of new AMCs by reinforcing the original aluminum matrix with hard metal carbides and silicon production waste in the form of silicate dust of various dispersions. In order to increase the productivity of the reinforcement process and the uniformity of mixing of the components, the reinforcement will be carried out by the liquid-phase method in a melting furnace of a special design. Various combinations and stoichiometric ratios of the composite components will be used in order to comprehensively assess the effect of reinforcing fillers on the structure and properties of the final AMC. The study is aimed at obtaining new high-quality AMC for subsequent industrial use, as well as at expanding the ways of recycling silicon production waste. |
| The purpose of the project | Obtaining new aluminum matrix composites (AMC) by reinforcing aluminum materials (α-Al) with fillers in the form of metal carbides (MeC) and superfine wastes of silicon production. |

| Expected project results |
2022 New promising combinations and stoichiometric ratios of the aluminum matrix and reinforcing fillers will be determined and selected. The possibilities and prospects of reinforcing high-purity aluminum and alloys of the Al-Mg-Si system with metal carbides and silicon production waste will be studied. A preliminary selection of new promising combinations and stoichiometric ratios of the aluminum matrix and reinforcing fillers will be carried out for laboratory experiments. 2023 Pilot batches of new aluminum matrix composites reinforced with metal carbides and silicon production waste will be obtained. Laboratory experiments will be carried out in a melting furnace of a special design for reinforcing high-purity aluminum and aluminum alloy of the Al-Mg-Si system with reinforcing fillers with their various combinations and stoichiometric ratios in an aluminum matrix. Experimental plastic deformation of new aluminum-matrix composites in deforming tools of a new design will be carried out with the production of prototypes. The structures and phase compositions of new alumina-matrix composites and the influence of reinforcing fillers on structural-phase transformations will be investigated. The physical-mechanical and casting properties of new aluminum matrix composites will be investigated. 1 (one) article will be prepared and published in a peer-reviewed foreign or domestic publication recommended by CQASES. A dissertation for the degree of Doctor of Philosophy (PhD) will be defended. 2024 Compositions of new experimental aluminum matrix composites will be optimized. A multivariate experiment will be carried out using data from previous experiments to optimize (correlate) the compositions of the obtained new alumina-matrix composites. Final optimized compositions of new aluminum matrix composites will be obtained. A thermodynamic analysis of the process of reinforcing aluminum materials will be carried out using optimized compositions of reinforcing fillers. Two (2) articles will be prepared and published in journals from the first three quartiles by impact factor in the Web of Science database or with a CiteScore percentile in the Scopus database of at least 50. A patent will be obtained from the Kazakhstan or Eurasian patent office. |
| The results achieved at the moment | The possibility of reinforcement of aluminum materials with metal carbides (SiC, B4C, TiC, WC, ZrC, Ti3SiC2, NbC, TaC, Al4C3, MoC), industrial wastes (red mud, fly ash, microsilica, spent catalyst, etc.) and their positive influence on the structure and properties of the final composite was revealed. ), as well as their positive influence on the structure and properties of the final composite at careful fulfillment of conditions of liquid-phase reinforcement, first of all, elimination of local agglomeration of reinforcing particles and ensuring the formation of crystallization centers (nucleation). Application of nanosilica and titanium-niobium carbide for liquid-phase reinforcement is practically absent in the available literature. The most promising interval parameters of liquid-phase reinforcement of high-purity aluminum and alloys of Al-Mg-Si system have been revealed: melting temperature 650÷850ºС; heating temperature of casting molds 250÷350ºС; stirring time 2÷10 min; stirring speed 300÷600 r/min; percentage compositions of micron carbide reinforcing materials in α-Al matrix 0,5÷30%; temperature of preliminary preparation of reinforcing materials 200÷400ºС. |
