Abstract
In both torsion and bending, the alloy exhibited a viscoelastic relaxa tion that could be modeled as a Debye peak superimposed on a power-law low-frequency background. In torsion, the relaxed and unrelaxed shear moduli were 9 and 12.2 GPa, respectively, maximum loss tangent was 0. 12. In bending, relaxed and unrelaxed Young's moduli were 15 and 35 GP a, respectively; maximum loss tangent was 0.11. Behavior was linear to at least 125 microstrain. These results are significant in that they represent a unique combination of stiffness and loss in a monolithic m aterial.
