摘要

It has been shown that, in some amorphous alloys, the value of initial bending stresses sigma(m) can influence the development of the relaxation of these stresses during the annealing of the alloys. These alloys include Co69Fe3.7Cr3.8Si12.5B11, with a nearly zero saturation magnetostriction (lambda(s) < 10(-7)) and the Fe78Ni1Si8B13 alloy with lambda(s) = 25 x 10(-6). In the iron-based Fe81Si4B13C2 and Fe57Co31Si2.9B9.1 alloys, no effect of the initial bending stresses on their relaxation has been observed. No this effect has also been observed in the metalloid-free alloys DD 3/4 80Mo10Zr10 and DD 3/4 80Mo8Ni2Zr10 with a nearly zero saturation magnetostriction lambda(s). When this effect manifests itself, the activation energy U of the given process becomes a function of two factors; i.e., this energy depends on both the composition of the alloy (that is, interatomic forces) and the value of the initial bending stresses. In this case, the activation energy U cannot be considered to be characteristic of the material.
