Aluminum Matrix Composite Material

The research involves studying the high-temperature chemical interaction of the Al-SiO2 system components. The high-temperature interaction of molten aluminum and silicon dioxide results in formation of aluminum matrix composite material containing silicon microparticles. The predominant linear size of silicon microparticles amounts to 3 - 5 microns, their mass fraction in the composite reaches 29 %.

High Temperature Synthesis

It was demonstrated that the application of self-propagating high-temperature synthesis as a low energy expenditure method to produce alloys of the Al-TiC system is of high priority. The process for the preparation of the charge and obtaining a composite alloywere described. The results of studies of electrical conductivity and mechanical properties of aluminum matrix composite alloys, modified with nanoparticles of titanium carbide TiC werepresented.Alloys with compositions: Al-10% TiC, Al7%Si + 10% TiC and Al9%Si + 10% TiC, as well as the original matrix materials: pure aluminum and Al9%Si werestudied. The index of plasticity was obtained by calculation. This calculated value showed that the experimental samples are small crystalline materials and nanomaterials. It was shown that the addition of nanoparticles of titanium carbide improves the mechanical properties of the initial alloy, without significantly reducing the electrical conductivity (no more than 30%).

Aluminum Matrix Composite Material

Friction stir welding of butt joints of aluminum-matrix dispersion-strengthened composite materials is considered. It is shown that with an increase in the content of strengthening SiC particles, the range of welding modes that ensure the formation of a joint without defects is significantly narrowed. It was found that under cyclic loads, welded joints begin to fail from the face of the weld. Keywords: friction stir welding, aluminum matrix dispersion-hardened composite material, mode, structure, roughness, strength. [email protected]
