The effect of different heat treatments on the piezomagnetic properties and magnetostriction of Fe73.5Cu1Nb3Si13.5B9 metallic glass were investigated as a function of the bias magnetic field.

Abstract
The effect of different heat treatments on the piezomagnetic properties and magnetostriction of Fe73.5Cu1Nb3Si13.5B9 metallic glass were investigated as a function of the bias magnetic field. The maximum values of the magnetomechanical coupling coefficient were equal to 0.15 for the as-quenched state, and 0.4 and 0.6 after annealing at 510 degrees C for 1/4 and 1 h, respectively. The magnetostrictive hysteresis loops were measured using the strain gauge method. The values of magnetostriction (lambda) at a magnetic field equal to about 3 kA/m in all cases were equal to about 22 X 10(-6).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
