摘要：

Stress-dependent damping in Cu-Be torsion and flexure suspensions has been measured at stresses up to 1.1 GPa, 95% of the yield stress. The modulus defects of Cu-Be increases from 4.3 X 10(-5) to only 6 X 10(-6) in this range. A much larger additional damping, originating at the clamping interface between the suspension and its support, was identified and eliminated.
