Proposed basic research project is dedicated to the study of reactions which take place during the process of formation of in-situ aluminum (Al) based composites prepared by reaction synthesis; microstructural and properties characterization of prepared in-situ composites. Used processing will yield in-situ composites, which residual porosity associated with in situ formation of new phases will be eliminated by applying of an external pressure already in the process of reaction synthesis. Depending on the physical state of the reactants during reaction synthesis project will be realized by three different approaches, which will be studied in parallel. A different method of in-situ formation strongly affects associated technology. A broad portfolio of different methods including powder metallurgy technology and reaction pressure infiltration of molten metal will be used. The outcomes of the project will be a new in-situ composites prepared in the form of profiles and castings with mechanical and thermal properties, and thermal stability and creep resistance exceeding the possibilities of conventional particulate Al based composites whilst cheaper technology of their production will be used. Such materials can find their application e.g. as parts of combustion engines (pistons, valves) wherein their use will lead to improved performance whilst saving cost and energy.
