Abstract
Abstract The Sn–3.8Ag-0.7Cu −1.0 wt% Zn (SACZ) plain solder alloy was reinforced by 0.3 wt% of TiO 2 nanoparticles (NP). SEM, XRD, DSC, and stress-strain characterization techniques were used to examine the synthesized samples. The morphology of the samples is uniform and the grain size of the SACZ-TiO 2 sample is refined compared to the plain solder. The TiO 2 addition improved the crystallinity of the SACZ sample. Furthermore, the melting temperature of the prepared samples has the same value even if its pasty range is decreased by adding TiO 2 NP. The mechanical properties of the examined samples were investigated at different temperatures and different strain rates. The activation energy (Q) of the SACZ-TiO 2 is lower than that of the SACZ sample. The results of this study confirm that the 0.3 wt% TiO 2 addition improves the physical properties of SACZ alloy.
