Mechanical damping is an important consideration in the design and analysis of dynamically loaded structures. For the aerospace structures of the future the potential payoff for high-damping structural materials is great: decreased complexity of control systems, increased reliability and decreased cost. In both torsion and bending, the Cd-Mg-alloy exhibited a viscoelastic relaxation 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 0.11. Behaviour 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 material.
