Description
Summary:The first order reaction kinetics was used to describe the irreversible structure relaxation, studied by means of the magnetic after-effect (MAE) measurements in the amorphous near-zero magnetostrictive Co)71.5)Fe)2.5)Mn)2)Mo)1 )Si)9)B)14) alloy. The long time (t)2)=2/25000s) measurements were performed at elevated temperatures: 379/520 K for the as-quenched and stabilized (annealed at 623 W/2h) samples. Basing on the Hesse-Rubartsch's method, the distribution range and the most probable value of the activation energy were calculated from isotherms. Three-peak activation energy spectra were obtained, which points to three different relaxation processes
