| Abstract: | This article gives a brief introduction to the dislocation damping mechanics of pure magnesium, magnesium alloys and magnesium based composites,and discusses the influence of ingredients,microstructure and micro-defects(including grain boundaries and phase boundaries)on the damping capacity of them. Due to multi-damping mechanics,magnesium based composites have higher damping capacity. |
