摘要
通过对铁磁合金的阻尼机理的综述,介绍了磁学-力学滞后阻尼的特征及其影响因素.它产生于应力诱导下的不可逆的磁畴壁的运动,阻尼性能受合金化学成分和热处理工艺的影响,合金的磁性参数和微观结构以及合金的内应力状态是决定阻尼大小的主要因素.
The damping mechanisms of ferromagnetic alloys are presented systematically in this paper, particularly on the characteristics and impact factors of the magnetomechanical hysteresis damping originating from the stress-induced irreversible movement of magnetic domain walls. The chemical composites and heat treatment can also affect the damping capacity, which depends primarily on the magnetic parameters, microstructures and internal stress in the alloys.
