摘要：
The effect of hot rolling and annealing on the damping behavior of Mg-Zr alloys was investigated. It was found that rolling lead to a significant grain refinement, and hence improved their tensile properties. In cast condition damping behavior was strain dependent. However, the damping behavior of the hot rolled alloys weakly depended on strain. This indicates that the damping capacity decreases after hot rolling. In contrast, annealing for the rolled alloy made the damping capacity increasing, but it didn't reach the as-cast level. The varieties of damping behavior can be explained by dislocation model of Granato and Lucke.
