Effect of Adding Micro Amount Rare Earth Element Er on Mechanical Property of Bi5Sb8Sn Solder Alloy

Abstract:

A new Bi5Sb8SnRE quaternary alloy was formed by adding 0.25wt%-0.75wt% rare earth (RE)Er into Bi5Sb8Sn solder alloy to study the effect of its mechanical property.The results show that adding micro amount of Er could refine the microstructure.Meanwhile,more uniform microstructure,improvements of the mechanical properties were obtained with Er additon.Comparing with Bi5Sb8Sn matrix, the tensile strength and shear strength increased by 41.8% and 83.0% respectively when Er adds up to 0.5wt.%; However,the Microstructure coarsened and the mechanical properties were decreased when the addition of Er more than 0.5wt.%.
