【摘要】 通过减落和电阻率的测量,研究非晶态合金(Fe_1-γCo_γ)₈₂Cu_0·tSi_4·4B_13·2（y=0,0.01,0·02,0.05,0·10）的结构弛豫。在25～350℃温区内,所有合金淬态和经退火处理后的弛豫谱都有两个峰。第一和第二峰的峰位温度或最可几激活能值Q_mp对Co含量（y）有不同的依赖关系。在驰豫谱第二峰出现的温区内,电阻率与温度的关系偏离线性,对y<0.05的合金还有小峰出现。更多还原

【Abstract】 Structural relaxation of (Fe_1-yCo_y)₈₂Cu_0.4Si_4.4 B_13.2 amorphous alloys（y = 0, 0.01, 0.02, 0.05, 0.01） is studied by measuring disaccommodation andresistivity, There are two peaks of relaxation spectra for all alloys whenthey are quenched and after annealing treatment in the temperature range 25℃--350℃. The Co constituent y dependence of peak temperature or the mostprobable value for the activation energy Q_mp is different at the first and thesecond peaks. The deyiation of linar temperature dependence of the resistivityand a little peak （for y<0.05 alloys） take place in the same temperaturerange with the second peak of the structural relaxation spectrum.更多还原
