摘要：The influence of mixture (La, Ce) rare earth elements (RE) on wettability and tensile property in Sn-3.5Ag solder alloy was investigated. The wetting property was improved by 0.25-0.5% addition of (La, Cc) rare earth elements into the Sn-3.5Ag solder alloy, while over addition of the rare earth elements up to 1.0 wt.% reduced the beneficial influence. The ultimate strength and ductility were also enhanced by 0.25-0.5% addition of (La, Ce) rare earth elements, while the change of melting temperature was negligible. (C) 2002 Elsevier Science B.V.
