摘要

本研究是以錳(Mn)元素取代Fe75Si10B15非晶質合金中部分鐵(Fe)元素(1-10at.%)，探討其結構演變及對其磁性的影響。以單輥熔射旋淬法(single roller melt-spinning method)製備(Fe1-XMnX)75Si10B15(X=0,0.01,0.03,0.05,0.07及0.1)之多成分合金薄帶。結果顯示合金薄帶其顯微組織為非晶結構且具有良好的軟磁性質，其飽和磁化強度(Ms)分佈由1.53至1.2T，矯頑磁力(Hc)由X=0的41.38A/m降至X=0.07的16.0A/m。DSC結果顯示錳(Mn)含量由X=0增加到X=0.1時，在X=0.03及X=0.05時其Tg分別為813K和781K，而Tx溫度則出現在801K到840K之間，X=0.05時非晶薄帶的ΔTx (=Tx-Tg)值為35K，而居里溫度Tc則由700K降至669K左右。在(Fe1-XMnX)75Si10B15非晶合金中，錳(Mn)元素置換量為5 at.%鐵(Fe)元素時，可有效地改善其玻璃形成能力及維持好的軟磁性質。

In this paper, the evolution of structure and magnetic properties of partial substitution of Fe(1-10 at.%) by Mn in the Fe75Si10B15 amorphous alloy was investigated. Multi-component alloy ribbons with compositions of (Fe1-XMnX)75Si10B15 (X=0, 0.01,0.03,0.05,0.07 and 0.1) were synthesized by single roller melt-spinning method. The XRD patterns of (Fe,Mn)-Si-B alloy ribbons only show a broad peak without the crystalline peak, indicating the formation of amorphous phase. In addition to the magnetic properties , it exhibit good soft magnetic properties of 1.53 to 12 T for saturation magnetization(Ms), 41.38 to 16 A/m for coercivity(Hc). The appearance of the glass transition (Tg) until X=0.03 , the Tg decrease from 813 to 781 K and Tx between 801 to 840 K, respectively, with increasing Mn content 0 to 0.1. The Mn-contenting metallic glassy alloy incurred the Curie temperature (TC) was from 700 K to 669 K. The partial replacement of Fe(5at.%) with Mn was very effective in improving glass-forming ability and soft magnetic properties of Fe75Si10B75 amorphous alloy.
