Abstract

The study compares the microstructure of the dispersion strengthened Cu – MgO composites prepared by thermo-chemical transformations of precursors and mechanical milling followed by spark plasma sintering technique. The effect of two different MgO contents (3 and 5 vol.%) on formation and stability of the copper matrix nanostructure is analysed. The structure development of the powder during its preparation and compact is characterised by metallographic observations and X-ray diffraction analysis. From the results follows that both the MgO contents are sufficient for effective strengthening the Cu – MgO nanostructure.

Keywords: Dispersion strengthened Cu – MgO, mechanical milling, X-ray diffraction analysis, thermal stability
