Temperature dependence of the viscoelastic response of In, Sn and In-Sn alloys

The elastic modulus and the internal friction of Sn and the γ-In-Sn phase are measured with a two-component piezoelectric oscillator at 50 kHz in the temperature range from 296 to 390 K. For both materials the viscoelastic responses at strains below 10-6 are described in terms of a Debye peak charac...
