摘　　要：原子缺陷对Fe-Al合金的力学和物理性能有重要影响,而内耗是对原子缺陷运动非常敏感的物理量。通过内耗特征的考查可以了解Fe-Al合金中原子缺陷的运动变化规律。对Fe-Al合金的内耗特征进行了分析,在总结与原子缺陷有关的3个内耗峰的主要特征和形成机理的基础上分析了以往研究中存在的争议和不足,并对今后的研究提出了建议。It has been well documented that the mechanical and physical properties of Fe-Al alloys are highly sensitive to the atomic defects. Internal friction has been proved to be a very useful measure of significant sensitivity for studying the atomic defects. Internal friction properties of Fe-Al alloys are examined to understand the evolution of the atomic defects. In this paper, a systematic discussion is made on the internal friction properties of Fe-Al alloys. Three intemal friction peaks correlated to atomic defects are found, the main features and the mechanisms are discussed. Based on these results, the disputes and shortages of previous work are analyzed. In addition, the suggestions for the further investigation are proposed.
