Investigation of microstructure and mechanical properties of novel Sn–0.5Ag–0.7Cu solders containing small amount of Ni
This work investigates the effect of (0.05–0.1wt.%) Ni additions on the SAC (0507) solder.
Enhanced strength of SAC (0507)–0.05Ni was due to microstructural refinement and uniform distribution of the IMCs.•
Improved ductility and worsen mechanical properties of SAC (0507)–0.1Ni alloy were due to the presence of large β-Sn grains.
Both YS and UTS increased with and decreasing temperature and decreasing strain rate
