Description
組成式が、(Fe100-a-b-c-d-eCraPbCcBdSie(a,b,c,d,eはat%))で示され、
0at%≦a≦1.9at%、1.7at%≦b≦8.0at%、0at%≦e≦1.0at%、であり、Feの組成比(100−a−b−c−d−e)は、77at%以上であり、
19at%≦b+c+d+e≦21.1at%であり、
0.08≦b/(b+c+d)≦0.43であり、
0.06≦c/(c+d)≦0.87であり、
ガラス転移点(Tg)を有することを特徴とするものである。これにより本発明のFe基非晶質合金によれば、ガラス転移点(Tg)を有するとともに、高い飽和磁束密度Bs、具体的には約1.5T以上のBsを得ることができる。そして本発明では、前記Fe基非晶質合金を粉末状にして結着材と混合し圧縮成形により磁心特性に優れた圧粉磁心を製造することができる。
本実施形態では、Cの組成比cを、0.75at%以上で13.7at%以下に設定し、更に、Bの組成比dを3.2at%以上で12.2at%以下に設定することが好適である。元素C及びBは共に半金属でこれら元素の添加により非晶質形成能を高めることができるが、これら元素の添加量が多すぎたり少なすぎると、ガラス転移点(Tg)が消失したり、あるいは、ガラス転移点(Tg)を発現させることができても他の元素に対する組成調整範囲が非常に狭くなってしまう。したがってガラス転移点(Tg)を安定して発現させるには元素C及びBの夫々を上記の組成範囲内に収めることが好ましい。またCの組成cは12.0at%以下とすることがより好ましい。またBの組成比dは、10.7at%以下とすることがより好ましい。
B2O3−SiO2)、ゾルゲル法により生成するガラス状物質(SiO2、Al2O3、ZrO2、TiO2等を主成分とするもの)等を挙げることができる。
以下、表1の組成を備えるFe基非晶質合金を、液体急冷法によりリボン状で製造した。具体的には、Fe−Cr−P−C−B−Siの溶湯をるつぼのノズルから回転しているロール上に噴出し急冷する単ロール法により、減圧Ar雰囲気下でリボンを得た。リボン製造条件としては、ノズルとロール表面との間の距離(ギャップ)を0.3mm程度、ロール回転時の周速を2000m/min程度、射出圧力を0.3kgf/cm2程度に設定した。
得られた各リボンの板厚は、20〜25μm程度であった。
また表1に示す密度Dは、アルキメデス法により測定した。
以下、表2の組成を備えるFe基非晶質合金を、水アトマイズ法により製造した。
なお、表2に示す各実施例では、いずれもガラス転移点(Tg)が得られた。
上記実験結果から、Pの組成比bは小さすぎると非晶質になりにくく、一方、大きすぎると飽和磁束密度Bsが小さくなることがわかった。
(液体急冷法で製造されたFe基非晶質合金の好ましい組成範囲について)
表1により、実施例におけるCの組成比cの好ましい範囲を、0.75at%≦c≦13.7at%とした。またBの組成比dの好ましい範囲を、3.2at%≦d≦12.2at%とした。
表2、図12に示すように、元素Pの組成比bを、4.7at%以上6.2at%以下の範囲とすることで非晶質で且つ約1.5T以上の飽和磁束密度Bsを得ることができるとわかった。
表1や表2の組成ではCrを1at%に固定したが、次の実験ではCrの組成比aを変化させた飽和磁束密度Bs及び表1と同じ特性の実験を行い、Crの組成比aを規定することとした。
実験では、表2に示すNo.94のFe基非晶質合金粉末(Fe77.9Cr1P6.3C5.2B9.2Si0.5;Bs=1.5T)を用いて実施例の圧粉磁心を製造した。
以下の表6は、バイアス磁界の大きさに対する各試料の透磁率μが掲載されている。
