通过对 Smith和 Birchak[1,2 ] 理论 ( SB理论 )的剖析 ,归纳总结了该理论中关于局部内应力的量值大小特性、不连续特性和状态分布特性 .比较了各种晶体缺陷对铁磁合金磁畴壁不可逆移动的影响 .提出了溶质原子局部内应力源模型 ,该模型可以很好地解释铁磁合金的阻尼性能 (内耗 )随退火温度升高而增大的实验规律
Based on the analysis of the theory of Smith and Birchak [1,2] (SB theory), the magnitude, discontinuity and state distribution of local internal stress in this theory are summed up.Compared the effect of various crystal defects on iron Magnetic alloy magnetic domain wall irreversible movement.This paper presents a solute atomic local stress source model that can be a good explanation for the ferromagnetic alloy damping performance (internal friction) with the annealing temperature increases the experimental law
