摘要：
The melting temperature and melting enthalpy of SnAg and SnAgCu (SAC) nanocrystals with diameters of approximately 30 nm was determined and, by means of Differential Scanning Calorimetry (DSC) a depression melting temperature of 7-10 degrees C was observed for both systems. The new experimental results were compared to the predicted values as well as available datasets. X-ray diffraction (XRD) analysis was performed to characterize the as-prepared and heat treated samples. Scanning electron microscopy (SEM and FE-SEM) analysis was carried out to study the morphology, microstructure and phase evolution of the as-synthesized particles before and after the heating process.
