Abstract
The effect of parameters such as strain amplitude, frequency and temperature on damping capacity of magnesium alloy AZ91D as-cast, solution and aged was investigated. Granato-Lücke model was employed to explain the influences of parameters on damping capacity of magnesium alloy. It is shown that solution treatment decreases the amount of second-phase particles distributing inside grains, weakens the strong pinning on dislocations, and increases the internal friction of AZ91D, while aging reduces the value due to precipitation of second-phase particles. The influence of solution treatment and aging on damping capacity of AZ91D at room temperature is the same as at 100 °C. The damping at 100 °C is greater than that at room temperature because of thermal activation.
