Abstract

In this study, the magnetoimpedance (MI) and stress impedance (SI) effect properties of Fe77.5Si7.5B15 wires have been investigated. Wires were annealed at 460 oC for different times. The largest change in the MI was observed at 1MHz ac current frequency value. At this frequency value, the change in MI was about 40% in the wire that as-received, while the change in the wire heat treated at 460 oC for 10 minutes was found to be 169%. It has been determined that low time annealed leads to increase in magnetic softness.

Keywords

FeSiB Tellerde Manyetoempedans ve Stresempedans Etki

Abstract

Bu çalışmada Fe77.5Si7.5B15 tellerin manyetoempedans (MI) ve stresempedans (SI) etki özellikleri incelenmiştir. Teller 460C de farklı sürelerde ısıtılmıştır. MI değerinde en büyük değişim 1MHz ac akım frekans değerinde gözlenmiştir. Bu frekans değerinde, ısıl işlem görmemiş telde MI değişimi yaklaşık %40 iken 460 C de 10 dakika ısıl işlem görmüş teldeki değişim %169 olarak bulunmuştur. Tellere uygulanan düşük süreli ısıl işlemlerin manyetik yumuşaklıkta artışa yol açtığı belirlenmiştir.

Keywords
