本文研究了零磁致伸缩金属玻璃Co65.2Fe4.2Ni3Nb1Al2Si9.8B14.8的应变感生磁各向异性Kus发展的动力学。Kus随退火时间ta的变化涉及宽的弛豫时间分布。对于440℃244MPa张力退火后的280—320℃155MPa等温张力退火,得到激活能ΔE=180—290kJ/mol而相应的指数前因子τo=10-14-10-22s的结果。The kinetics of development of strain-induced magnetic anisotropy Kus has been studied in a zero-magnetostriction metallic glass Co65.2Fe4.2Ni3Nb1Al2Si9.8B14.8. The variations of Kus with annealing time ta involve the effect of a wide distribution of relaxation times. It was found that △E = 180-290kJ/mol and τ0=10-14-10-22s for 155 MPa isothermal annealing at 280-320℃ after 244MPa annealing at 440℃.
