摘要：

The dependence of frequency over a range of 0-3 KHz on Young's modulus and internal friction in Sn-9Zn and Sn-3.5 Ag, eutectic lead free solders was discussed. The stress deformation curve was measured by three point bend testing and the static Young's modulus was calculated from the slope of a straight line in the range of strain less than 10-4. With the increase of frequency, the young's modulus and the internal friction of all the solders increased and decreased. The result shows that the statistically measured value of Young's modulus exhibited an isothermal modulus and vibrationally measured shows an adiabatic modulus.
