Description
タウ∝exp(−Ea/kBT)、
[式中、タウは、温度Tでエージングプロセスが完了するための時間であり、Eaは、エージングプロセスのための活性化エネルギーであり、kBは、ボルツマン定数である。]。対数目盛でプロットしたデータを、広く使用されている磁気装置、例えば変圧器の動作温度に妥当な温度に外挿した。この種類のプロットは、アレニウスプロットとして周知であり、材料の長期にわたる熱的挙動を予測するために産業界において広く周知である。動作温度150℃を選択し、というのは、こうした磁気装置において使用される電気絶縁性材料の大部分は、約150℃を超えると燃焼するかまたは急速に劣化するからである。表IVは研究の結果であり、これは、本発明の具体例に従うアモルファス合金は、150℃で100年よりもはるかに長く熱的に安定であることを示す。
約60kgの成分金属、例えばFeB、FeSi、Fe及びCをるつぼ中で溶解し、溶融金属を、米国特許第4,142,571号において説明する方法によって急速に凝固した。形成されたリボンは幅約170mm及び厚さ約25μmを有し、そのアモルファス構造を保証するために並びにリボン材料のキュリー温度及び結晶化温度を決定するために、従来の示差走査熱量測定法によって試験された。従来のアルキメデスの方法を使用して、質量密度を決定し、これは、材料の磁気キャラクタライゼーションのために必要だった。リボンは延性があることが見い出された。
170mm幅のリボンを25mm幅のリボンに切断し、各々重量約60グラムのトロイド形の磁心を巻くために使用した。コアを、本発明の具体例の合金の場合、300〜370℃で1時間、トロイドの円周方向に沿って適用した30Oe(2400A/m)のDC磁場中で、及び市販のメトグラス(登録商標)2605SA1合金の場合、360℃〜400℃で2時間、トロイドの円周方向に沿って適用した30Oe(2400A/m)のDC磁場中で、熱処理した。磁気測定のために、10巻きの一次銅ワイヤ巻線及び10巻きの二次巻線を、熱処理したコア表面に適用した。加えて、長さ230mm及び幅85mmの寸法のリボン条片を、本発明の具体例のアモルファス合金及び市販のメトグラス(登録商標)2605SA1合金から切断し、本発明の具体例のアモルファス合金の場合300℃と370℃との間及び市販の合金の場合360℃と400℃との間の温度で、両方とも条片の長さ方向に沿って適用した約30Oe(2400A/m)のDC磁場を用いて熱処理した。
実施例IIの一次及び二次銅巻線を有する熱処理した磁心の磁気キャラクタライゼーションを、DC及びAC励起能力を有する市販のBHループトレーサーを使用することによって実行した。AC磁気特性、例えば鉄損を、50/60Hz測定の場合のASTM A912/A912M−04規格に従うことによって調べた。長さ230mm及び幅85mmを有する実施例IIの焼なまししたまっすぐの条片の磁気的性質の例えばAC鉄損を、ASTM A932/A932M−01規格に従うことによって試験した。
実施例IIIの十分にキャラクタライゼーションされたコアを、250℃を超える温度での加速エージング試験のために使用した。試験の最中に、コアは60Hzで励起場中にあり、磁気誘導約1Tに誘導して、高温での実際の変圧器動作をシミュレートした。
