Abstract Scope Metal matrix composites based on aluminum have high specific strength, hardness and wear resistance, fatigue strength. Shear deformation under pressure due to high shear strains allows not only to form a nanostructure, but also to join immiscible metals. Here we report the results obtained on sandwich-type Al-Cu-Al composite samples obtained by shearing under pressure of the initial coarse-grained aluminum and copper plates. The values of the composite tensile strength reached 485 MPa, which is several times higher than in pure aluminum (80 MPa) and copper (190 MPa) subjected to the same processing. Such an increase in the ultimate strength is associated with the formation of a multiphase fine grained structure and a some change in the deformation mechanism. The present work was accomplished according to the state assignment of IMSP RAS and supported by the Russian Science Foundation (Grant No. 18-12-00440)
