Abstract Two interfacial reactions of the eutectic Sn-Zn alloy as filler on the Al substrate during soldering were indicated, i.e., Zn in filler penetrating into Al grain boundaries to form Al-Zn solid solution, and some needle-like Al-Sn-Zn solid solution phases forming and growing into Sn-Zn solid solution. The above reactions make the bonding between filler and substrate to be strengthened more and more.Correspondent: CHEN Rong,(Department of Chemistry, Peking University, Beijing 100871)
