Abstrakt: This work measures and studies the high-temperature spectrum of elastic energy absorption in tin. Its features are exhibited and new effects are discovered at ∼433, 483, and 543 K (peaks A, B, and C), the physical natures of which are explained: peak A by polymorphous β-γ-transformation, peak B most likely by stress relaxation caused by this transformation, and peak C by a change in the short-range order in the melt. A connection is also established between the β-γ-transformation with the material's aging and purity. [ABSTRACT FROM AUTHOR]
