| Pure aluminum with graphite coated silver nanoparticles (∼ 10 nm) composites were prepared by mechanical milling, cold compacted, sintered and hot extruded. Transmission electron micrographs and energy dispersive spectroscopy showed that nanoparticles were homogeneously dispersed into the aluminum matrix and did not coalesce, grow or dissolve on it because of their graphite coating. Within the range 0-2 silver nanoparticles weight percentage, mechanical properties such as Yield strength (sy), maximum strength (smax) and micro hardness (VHN) were improved, compared to the as annealed aluminum properties. |
