DISACCMMODATION PHENOMENON IN METALLIC GLASS (Fe0.8Ni0.15Cr0.05)78Si8B14
金属玻璃(Fe0.8Ni0.15Cr0.05)78Si8B14的起始磁导率减落现象

Disaccommodation (DA) of initial permeability of metallic glass (Fe0.8Ni0.15Cr0.05)78Si8B14 was measured at various temperatures in the range of 77-553 K. The measurements have shown that DA exhibits an asymmetric spectrum with a single relaxation peak. Kinetic behaviour of DA was examined at 273 K. An asymmetric activation energy spectrum with a single peak and the most probable activation energy of 1.40 eV was obtained by fitting a kinetic curve of DA by means of Hesse-Rubartsch's method. Effect of annealing on DA and kinetic behaviour of the annealing were examined. It was shown that the annealing essentially affects on DA and the kinetice behaviour of the annealing is approximateiy governed by Int kinetics.
