摘要
Abstract
The Mg-6Gd-3Y-0.5Zr magnesium alloy had been used in aerospace structural products,its internal damping performance was directly related to the dynamic characteristics and response of structures,the internal damping performance of Mg-6Gd-3Y-0.5Zr magnesium alloy was studied using DMA tester and the mechanism was analyzed.The results show that the damping of Mg-6Gd-3Y-0.5Zr alloy gradually increases with the increase of strain amplitude and the mechanism at temperature conforms to the G-L dislocation damping theory.The damping performance of alloy gradually increases with the increase of temperature.Within the tested frequency range of 1～80 Hz,the lower the frequency is,the more sensitive the damping is to the change of temperature,and the influence of temperature on damping performance conforms to the Schoeck theory.关键词
