| 基金项目： | The authors would like to thank Mr. Volker Kree from the Center for Magnesium Technology, GKSS Research Center, for the performance of the hardness measurements shown in this paper. |
| 摘 要： | The effect of isochronal heat treatments for 1h on variation of damping, hardness and microstructural change of the magnesium wrought alloy AZ61 was investigated. Damping and hardness behaviour could be attributed to the evolution of precipitation process. The influence of precipitation on damping behaviour was explained in the framework of the dislocation string model of Granato and Lücke. |
