Study the effect of adding nano-magnesium oxide on some structural and mechanical properties of (Cu-10%Fe)

Metallurgy Powder is employed appropriately in line with industrial development and practicality in order to produce samples with unique properties and ease of application. This technology was used to prepare copper matrix composites with a fixed rate of 10 wt.% (Fe) and (2, 4, 6, 8,10)wt.% of magnesium oxide particle (MgO) as corroboration material. The metal powders were milled together for two hours in order to be homogenized. The prepared powder samples were pressed at 5 tons for only one minute. Then the pressed samples were sintered at( 900°C) for 2 hr. After that, some mechanical properties (represented by hardness, compressive strength, and wear) and scanning electron microscope properties (SEM) were examined. The results showed that the best hardness values obtained were at 10wt.% of MgO, reaching 320Hv before treatment and 480Hv after treatment. As for the results of compressive strength, the value was 53MPa before treatment and 75MPa after treatment at the same percentage of corroboration material. While wear reached the lowest value of (6.9×10-8 g/cm) before treatment and (5.1×10-8 g/cm) after treatment at the best corroboration rate of 10 wt.%. Concerning the scanning electron microscope (SEM) results, they best agglutination and clear overlay amid the granular limits as a result of this strong attachment and sameness among the mechanisms of the elements.
