dc.description.abstractIn this study, various contents of graphene nanosheets (GNS) were successfully incorporated into Sn-0.7Cu base alloy by powder metallurgy (PM) technique to form Sn-0.7Cu-xGNS composite materials. The synthesis process included mixing and mechanical alloying, compacting and sintering. The effects of GNS on the microstructure, wettability, microhardness and melting properties were investigated. Optical and scanning electron microscopy (SEM) with energy-dispersive spectroscopy (EDS) revealed that the distribution of GNS in the solder matrix became more evident as the content of GNS increased. The reinforcement particles were homogeneously distributed at the grain boundaries, resulting in a finer β-Sn structure. The melting temperatures of the synthesized composites, determined by differential scanning calorimetry (DSC), are slightly higher than those of the Sn-0.7Cu base alloy. Incorporating GNS into the Sn-0.7Cu matrix enhanced microhardness up to 15.65% and reduced the contact angle between the composite solder and copper substrate up to 48.6%, significantly improving wettability.
