Abstract

The effects of 0.5 wt. % In as well as 0.5 wt. % In and 1 wt. % Zn double (In & Zn) additions to eutectic Sn58Bi alloy on the microstructure and mechanical properties were studied before and after thermal aging. Newly designed In & Zn-added Sn58Bi alloy showed much finer microstructure than eutectic Sn58Bi and In-added Sn58Bi alloys. The elongation improvements of 36 % and 41 % before and after 1008 h aging were obtained in In & Zn-added Sn58Bi alloy compared to eutectic Sn58Bi alloy. In induced solid solution softening (SSS) effect on Sn phase was revealed by nanoindentation tests. A hardness decrease and a large creep displacement were obtained in both In-and In & Zn-added Sn58Bi. The effects of Zn and In were combined responsible for the elongation improvement of In & Zn-added Sn58Bi.
