Abstract


It is researched the influence rule on piezomagnetism property of Fe73.5CulNb3Si13.5B9 amorphous alloy with technology for heating processing. Result shows that the piezomagnetism property of Fe-based amorphous alloys appears favorable property at frequency of 1 KHz. Elevating the temperature of heating processing is in favor of promoting the piezomagnetism effect. In the condition of frequency at 1KHz, and continuous upload/offload stress applying process, the piezomagnetism property of Fe73.5CulNb3Si13.5B9 amorphous alloy is enhanced with increase of heating treatment temperature. When the temperature rise at 550 ℃, stress impedance (SI) effect value SI(%)=1.402 (relevant applying stress σ=0.612MPa). SI effect of Fe-based amorphous alloy is more sensitive under the stress of 0.2 MPa than above.
