将金属在冷加工条件下的内摩擦和动模量的复杂性分为以下三种不同的效应，可以很好地理解：(1)“非线性”效应，其特征是强烈的振幅依赖性和频率独立性，并且在严重变形后消失；(2)在远低于再结晶温度时，变形后迅速恢复的Koster效应；(3)“粘度”效应，具有较强的频率和温度依赖性。本文从位错理论的角度简要讨论了这些效应的来源。
The complexities of the internal friction and dynamic modulus of metals in the cold‐worked condition may be understood reasonably well by separation of the phenomena into the following three distinct effects: (1) the ``nonlinear'' effect, characterized by strong amplitude dependence, frequency independence, and its disappearance after severe deformation; (2) the Koster effect, which shows rapid recovery after deformation, at temperatures well below the recrystallization temperature; (3) the ``viscosity'' effect, characterized by strong frequency and temperature dependence. The origin of each of these effects is briefly discussed from the point of view of dislocation theory.
