A ZrO 2 nanoparticles strengthened lead-free Sn-3.5Ag-ZrO 2 solder was prepared by mechanically stirring ZrO 2 nanoparticles into the molten melt of eutectic Sn-3.5Ag alloy. The influence of ZrO 2 nanoparticles on the eutectic solidification process, in particular the formation of Ag 3 Sn intermetal
