Research Status of the Damping Mechanism on Magnesium and Magnesium Alloys
摘 要
综述了室温下镁及镁合金阻尼机理研究的现状, 针对目前阻尼模型与实测数据之间有较大误差的现象, 阐明了G-L模型是研究镁合金阻尼机理的重要基础, 但不能完全解释阻尼机理; 针对该问题, 提出了以镁合金全部振动变形过程的振动阻尼模型为研究目标, 以内部位错随着振动变形过程的进行(应变振幅增大)其数量和形态的变化模式为切入点, 以位错的变化导致镁合金内部能量的变化模式为研究思路, 对镁合金的阻尼机理进行建模。

Abstract
The research status of damping mechanism on magnesium and magnesium alloys at room temperature is reviewed. Considering the phenomenon of greater error between damping model and measured data at present, the paper illuminates that the G-L model is an important foundation of studying damping mechanism, but it can′t interpretate the damping mechanism completely. Aiming at this problem, taking the damping model of magnesium alloy vibration deformation process as a target, using the variation pattern of quantity and morphology of inner dislocation during vibration deformatin progress as a cutting point, the variation pattern of magnesium alloys inner energy variation caused by dislocation as research thoughts, the model of damping mechanism of magnesium alloys was established.
