MECHANICAL PROPERTIES
The current demand for stronger and lighter materials has allowed the generation of new materials that combine high resistance with low densities, an example of these materials are nanocomposites, which are obtained by combining one or more materials with sizes around of nanometers into a bulk material, this nanocomposites gives properties different from those presented individually. Nanocomposites of Al alloy 7075 were produced by introducing into the matrix a second phase particles of nanometer size by the technique of powder metallurgy to increase their mechanical properties. The dispersion of silver nanoparticles coated with carbon (Ag-C NP) within the matrix of 7075 aluminum (Al7075) was performed by mechanical milling in a SPEX mill of high energy milling for different times (5 and 10 h), powders were compacted under uniaxial compression at 950 MPa to obtain a pellet of 4 cm in diameter, sinterized in an argon atmosphere for 24 h and finally indirect hot extrusion at 773 K with a dice with circular aperture and a ratio of 25:1 allowed to produce bars of 1 cm in diameter and about 50 cm long.
