Abstract

New data were obtained on the effect of small additions of magnesia nanoparticles on the mechanical properties of aluminum. Composite specimens were produced by cold pressing of aluminum powders with or without copper added with subsequent sintering in a forevacuum. As a result, a significant increase was detected in the strength properties of materials modified by magnesia nanoparticles, namely, in tensile, compressive, flexural, and offset yield strengths.
