Abstract: The paper describes the production of aluminum matrix composite materials containing metallic glass particles of the composition Fe$_{66}$Cr$_{10}$Nb$_5$B$_{19}$ by successively applying mechanical activation of the initial powders in a planetary mill and spark sintering. During sintering at 540$^{\circ}$C, the metallic glass particles are completely or partially converted into the intermetallic compound Fe$_4$Al$_{13}$. Composite materials sintered from a mixture of Al + 20 (vol.)% Fe$_{66}$Cr$_{10}$Nb$_5$B$_{19}$ are characterized by anisotropy of mechanical properties: the yield strength in compression, microhardness and deformation at failure in the pressing direction during sintering are 550 MPa, 200 HV and 14.2%, respectively, while in the direction perpendicular to the pressing direction, these characteristics are 740 MPa, 250 HV and 2.2%.

Keywords: composite materials, aluminum, intermetallic compounds, metallic glass, spark sintering, mechanical activation.
