摘要 首次研究了铝锂合金的阻尼特性,对四元铝锂合金的阻尼温度谱、频率谱和振幅谱取得了明确的认识。分析了阻尼的起因,特别对第二相沉淀体引起的阻尼现象作了研究。指出位于240℃附近的δ阻尼峰是应力诱导下δ′相界面运动的结果。文中还指出了合金弹性模量与阻尼行为的矛盾关系。 The damping characteristic of aluminium-lithium alloys was studied for the first time. Clear konwledge was obtained on the temperature spectra, frequency spectra and strain amplitude spectra of damping capacity of quaternary aluminium ys. The cause of damping was analyzed and the damping phenomena due to the second phase particles were specially studied. It is pointed out that the δ peak(at 240℃ or so)is due to the stressinduced phase boundary movements. The papor also shows the contradiction relationship between elastic modulus and damping capacity.
