The study is devoted to the study of mechanical properties under uniaxial tension and compression of polycrystalline structures based on intermetallic compounds of titanium aluminides (TiAl3, Ti3Al) and nickelide (TiNi3) through molecular dynamic modeling. These alloys are of considerable interest as promising structural materials. The structural, elastic, and mechanical characteristics of these intermetallides reinforced with carbon nanotubes (CNTs) have been studied using the molecular dynamics method. The choice of CNTs as a reinforcing component is due to their unique properties, including high tensile strength, low density, significant modulus of elasticity and high aspect ratio. The results demonstrate that the introduction of carbon nanotubes significantly increases the mechanical strength of composites. Keywords: polycrystal, modeling, mechanical properties, aluminides, nickelides.
