Abstract

This study shows the feasibility of the introduction of Al₂O₃ nanoparticles by mechanical alloying in a near eutectic Ag-3,5Sn solder alloy. Different weight percents of Al₂O₃ were dispersed and the resulting microstructures were analyzed using optical and electronic microscopy and X-ray diffraction. The alloys with 1 and 5 wt% have shown excellent results regarding nanoparticle dispersion and microstructure homogeneity after 100h of high energy milling.
