研究了金属玻璃Fe_(78)Si_(10)B_(12)的磁化惑生各向异性常数K_(um)和应变感生各向异性常数K_(us)的350℃等温退火动力学行为和随测量温度T的变化,具有正值的K_(um)以lgta的线性函数随退火时间ta变化,而正比于M_s~(4.6)(T)随T变化,具有负值的K_(us)对于退火时张力的施加和去除作可逆的弛豫变化,而正比于M_s~(7.5)(T)随T变化,用一种畸变方向有序模型对结果作了定性解释。
The kinetics of isothermal annealing at 350 ℃ for the magnetization of K_ (um) and strain-induced anisotropy constant K_ (us) of metallic glass Fe_ (78) Si_ (10) B_ The change of measurement temperature T, K_ (um) with a positive value of lgta linear function with annealing time ta change, and proportional to M_s ~ (4.6) (T) with T changes, with negative K us (us) for annealing The application and removal of the tension at the moment change irreversibly, which is proportional to the change of M_s ~ (7.5) (T) with T, and the result is qualitatively explained by a distorted orientation model.
