The effects of graphene nano-platelets amounts and mechanical alloying duration on the microstructural and mechanical properties of aluminum were investigated. The characterization studies were performed by X-ray diffractometry, Raman spectroscopy, scanning electron microscopy/energy dispersive spectrometry, particle size analysis, differential scanning calorimetry, Archimedes' density and microhardness test method. The microhardness of composites increased gradually by the addition of 0.5 and 1 wt.-% GNP, whereas an adverse effect was observed by the increment of the GNP amount to 2 wt.-%.eninfo:eu-repo/semantics/closedAccessAluminum matrix compositesgraphene nano-platelet (GNP)mechanical alloyingmicrostructuremechanical propertiesArticle10.3139/120.1109445811-12946952WOS:000388870700005Q4Q2
