文摘

Pure Bi and Sn and four Bi–Sn alloys distributed on the entire concentration range were selected for internal-friction investigation over a wide temperature range. There exist two peaks in the plots of internal friction versus temperature for liquid Sn, Bi–Sn60 and Bi–Sn90 alloys, one peak being located at about and another at about . Only a single internal-friction peak at about occurs in liquid Bi–Sn43 (eutectic composition). No internal-friction peak appears in liquid Bi–Sn20 alloy and pure Bi. The height of the internal-friction peaks depends on the content of Sn. The present finding suggests that Sn-rich Bi–Sn alloys may inherit the internal-friction behaviors of pure Sn, whereas Bi-rich Bi–Sn alloy seems to be like pure Bi. The position of the internal-friction peaks is frequency dependent, which resembles the internal-friction feature in structure transition in solids.
