Abstract

The magnetostriction of Fe73.5CU1Nb3Si15.5B7 metallic glass, annealed in a vacuum for l h at temperatures from 300 to 650 °C, was measured using a strain gauge method. The maximum values of the magnetostriction coefficient for technical saturation (at Hmax = ~2.9 kA/m) slowly decreased from approximately 25 ± 2 × 10−6 after annealing at 300 °C, to approximately 21 ± 2 × 10−6 after annealing at 560 °C, and rapidly to about 2 ± 2 X 10−6 after annealing at 600 °C. After annealing at 650 °C, the magnetostriction increased to about 6 ± 2 × 10−6. The decrease in the magnetostriction is connected with an increase in crystallization.
