Improving the strength properties of aluminum powder materials by the addition of magnesium oxide nanoparticles

Cover Page

Abstract


New data were obtained on the effect of small additions of magnesium oxide nanoparticles on the mechanical properties of aluminum. For the preparation of samples of composites, cold pressing and sintering of powdered aluminum, including those with copper, were used in the forvacuum. As a result, a significant increase in the strength properties of materials modified with magnesium oxide nanoparticles was found: tensile strength, compression, bending strength, and yield strength.
