The experimental samples of furnace charge of composite structure of 9 % of Ag + 10 % of Y2O3, and for comparison, of powder of pure MDS-1 silver were made with methods of powder metallurgy. Influence of the strengthening nanopowder Y2O3 additive on a compressibility and mechanical properties of disperse strengthened compact materials on the basis of silver is investigated. Composite powder in parameters of pressing concedes to powder of pure silver, with a pressure of pressing of 600 MPa on silver furnace charge density 95,2 %, on composite in the same conditions — 81,7 %. The maximum of hardness of the composite samples pressed under pressure of 600 MPa and baked at temperature of 800 arcC is equal to 318 MPa that twice exceeds the hardness of control compacts from pure silver.
